How Do Dudes Pee? An Earth-Shattering Reveal - Hell Gate
The men of Hell Gate explain things to me.

So I made a horrible horrible mistake a couple months ago; my daughter and I were playing Valheim, and she mentioned wanting to play Baldurs Gate.
So I got it for her as a late birthday present.
Thus ended our Valheim sessions as she was sucked into BG. 😂
I really should’ve seen that coming.
We have reached a detente; she’ll play some Valheim with me if I play some Baldurs Gate while she watches.
This is how people end up as streamers, isn’t it? 😂

While sitting on the tarmac at Austin’s airport waiting for our gate to become available, I decided to find a public transportation option to get to downtown Austin. Google Maps suggested I walk to neighboring Travis County Correctional Complex and catch a bus from there. Only 4½ hours total.

Overlapping Top Gate Electrodes based on Low Temperature Atomic Layer Deposition for Nanoscale Ambipolar Lateral Junctions
We present overlapping top gate electrodes for the formation of gate defined lateral junctions in semiconducting layers as an alternative to the back gate/top gate combination and to the split gate configuration. The optical lithography microfabrication of the overlapping top gates is based on multiple layers of low-temperature atomic layer deposited hafnium oxide, which acts as a gate dielectric and as a robust insulating layer between two overlapping gate electrodes exhibiting a large dielect…

I would not go to any store that does that. Also would ask fire services if that was a safety hazard. Those who are visually impaired would not be able to use it.

Phase transition in magic with random quantum circuits
Magic is a property of quantum states that enables universal fault-tolerant quantum computing using simple sets of gate operations. Understanding the mechanisms by which magic is created or destroyed is, therefore, a crucial step towards efficient and practical fault-tolerant computation.

In this work, we propose a dual-port cell design to address the pass disturb in vertical NAND storage, which can pass signals through a dedicated and string-compatible pass gate. We demonstrate that: i) the pass disturb-free feature originates from weakening of the depolarization field by the pass bias at the high-${V}_{TH}$ (HVT) state and the screening of the applied field by channel at the low-${V}_{TH}$ (LVT) state; ii) combined simulations and experimental demonstrations of dual-port desig…

Scanning gate microscopy of nonretracing electron-hole trajectories in a normal-superconductor junction
We theoretically study scanning gate microscopy (SGM) of electron and hole trajectories in a quantum point contact (QPC) embedded in a normal-superconductor (NS) junction. At zero voltage bias, the electrons and holes transported through the QPC form angular lobes and are subject to self-interference, which marks the SGM conductance maps with interference fringes analogously as in normal systems. We predict that for an NS junction at non-zero bias a beating pattern is to occur in the conductanc…

Temporal quantum eraser: Fusion gates with distinguishable photons
Linear-optics gates, the enabling tool of photonic quantum information processing, depend on indistinguishable photons, as they harness quantum interference to achieve nonlinear operations. Yet the required indistinguishability is related to the symmetry of the multiphoton wavefunction, and does not necessarily imply identical photons. Here we show for the case of two-photon gates that the ideal gate operation can be retrieved if one can guarantee the exchange symmetry of the input photonic sta…

Nice to see a good, detailed answer to a question in my mind ---
https://www.sfgate.com/bayarea/article/could-sf-golden-gate-bridge-collapse-19370020.php

Yesterday I needed to drive my Elise about 150miles to get to today’s Sonoma Raceway event, on new slick tires, and it was raining. I went slowly up the coast road, stopped a few times and made it to the hotel ok. It was dry north of Half Moon Bay and I got a nice pic of the Golden Gate Bridge and SF. Just had my first track session (it’s dry today) and am slowly learning the track. #carsofmastodon

Towards Utilizing Scanning Gate Microscopy as a High-Resolution Probe of Valley Splitting in Si/SiGe Heterostructures
A detailed understanding of the material properties that affect the splitting between the two low-lying valley states in Si/SiGe heterostructures will be increasingly important as the number of spin qubits is increased. Scanning gate microscopy has been proposed as a method to measure the spatial variation of the valley splitting as a tip-induced dot is moved around in the plane of the Si quantum well. We develop a simulation using an electrostatic model of the scanning gate microscope tip and …

Classical certification of quantum gates under the dimension assumption
We develop an efficient method for certifying single-qubit quantum gates in a black-box scenario, assuming only the dimension of the quantum system is known. The method is based on testing the outcomes of exact quantum computations on a single qubit, with no auxiliary systems required. We prove that the method's sample complexity grows as $\mathrm{O}(\varepsilon^{-1})$ with respect to the average gate infidelity $\varepsilon$ for the certification of a relevant single-qubit gate, which experime…

Gate-defined quantum point contacts in a germanium quantum well
We report an experimental study of quantum point contacts defined in a high-quality strained germanium quantum well with layered electric gates. At zero magnetic field, we observe quantized conductance plateaus in units of 2$e^2/h$. Bias-spectroscopy measurements reveal that the energy spacing between successive one-dimensional subbands ranges from 1.5 to 5\,meV as a consequence of the small effective mass of the holes and the narrow gate constrictions. At finite magnetic fields perpendicular t…

Multi-controlled Phase Gate Synthesis with ZX-calculus applied to Neutral Atom Hardware
Quantum circuit synthesis describes the process of converting arbitrary unitary operations into a gate sequence of a fixed universal gate set, usually defined by the operations native to a given hardware platform. Most current synthesis algorithms are designed to synthesize towards a set of single qubit rotations and an additional entangling two qubit gate, such as CX, CZ, or the Molmer Sorensen gate. However, with the emergence of neutral atom based hardware and their native support for gates …

3D ferroelectric phase field simulations of polycrystalline multi-phase hafnia and zirconia based ultra-thin films
HfO$_2$- and ZrO$_2$-based ferroelectric thin films have emerged as promising candidates for the gate oxides of next generation electronic devices. Recent work has experimentally demonstrated that a tetragonal/orthorhombic (t/o-) phase mixture with partially in-plane polarization can lead to negative capacitance (NC) stabilization. However, there is a discrepancy between experiments and the theoretical understanding of domain formation and domain wall motion in these multi-phase, polycrystallin…

Better Optimization of Variational Quantum Eigensolvers by combining the Unitary Block Optimization Scheme with Classical Post-Processing
Variational Quantum Eigensolvers (VQE) are a promising approach for finding the classically intractable ground state of a Hamiltonian. The Unitary Block Optimization Scheme (UBOS) is a state-of-the-art VQE method which works by sweeping over gates and finding optimal parameters for each gate in the environment of other gates. UBOS improves the convergence time to the ground state by an order of magnitude over Stochastic Gradient Descent (SGD). It nonetheless suffers in both rate of convergence …

Gate-tunable subband degeneracy in semiconductor nanowires
Degeneracy and symmetry have a profound relation in quantum systems. Here, we report gate-tunable subband degeneracy in PbTe nanowires with a nearly symmetric cross-sectional shape. The degeneracy is revealed in electron transport by the absence of a quantized plateau. Utilizing a dual gate design, we can apply an electric field to lift the degeneracy, reflected as emergence of the plateau. This degeneracy and its tunable lifting were challenging to observe in previous nanowire experiments, pos…

Restricted Randomized Benchmarking with Universal Gates of Fixed Sequence Length
The standard randomized benchmarking protocol requires access to often complex operations that are not always directly accessible. Compiler optimization does not always ensure equal sequence length of the directly accessible universal gates for each random operation. We introduce a version of the RB protocol that creates Haar-randomness using a directly accessible universal gate set of equal sequence length rather than relying upon a t-design or even an approximate one. This makes our protocol …

Tunable nonlinear excitonic optical response in biased bilayer graphene
Biased bilayer graphene (BBG) is an important system for studies of excitonic effects in graphene--based systems, with its easily tunable bandgap. This bandgap is governed by an external gate voltage, allowing one to tune the optical response of the system. In this paper, we study the excitonic linear and nonlinear optical response of Bernal stacked BBG as a function of the gate voltage, both for in--plane (IP) and out--of--plane (OOP) directions. Based on a semi-analytical model of the electro…

Design Constraints for Unruh-DeWitt Quantum Computers
The Unruh-DeWitt particle detector model has found success in demonstrating quantum information channels with non-zero channel capacity between qubits and quantum fields. These detector models provide the necessary framework for experimentally realizable Unruh-DeWitt Quantum Computers with near-perfect channel capacity. We propose spin qubits with gate-controlled coupling to Luttinger liquids as a laboratory setting for Unruh-DeWitt detectors and general design constraints that underpin their f…

Robust and fast microwave-driven quantum logic for trapped-ion qubits
Microwave-driven logic is a promising alternative to laser control in scaling trapped-ion based quantum processors. However, such electronic gates have yet to match the speed offered by their laser-driven counterparts. Here, we implement Mølmer-Sørensen two-qubit gates on $^{43}\text{Ca}^+$ hyperfine clock qubits in a cryogenic ($\approx25~\text{K}$) surface trap, driven by near-field microwaves. We achieve gate durations of $154~μ\text{s}$ (with $1.0(2)\%$ error) and $331~μ\text{s}$ ($0.5(…

Demonstration of system-bath physics on gate-based quantum computer
We demonstrate algorithmic cooling on IBM-Q devices. We utilize inherent qubit noise to simulate the equilibration of an interacting spin system towards its ground state, when coupled to a dissipative auxiliary-spin bath. The steady-state correlations in the system are defined by the system Hamiltonian and are stable as long as the algorithm can be executed. In particular, we demonstrate the relaxation of system spins to ferromagnetic and antiferromagnetic ordering, controlled by the definition…
