Quantum Algorithm for Protein Side-Chain Optimisation: Comparing Quantum to Classical Methods
Modelling and predicting protein configurations is crucial for advancing drug discovery, enabling the design of treatments for life-threatening diseases. A critical aspect of this challenge is rotamer optimisation - the determination of optimal side-chain conformations given a fixed protein backbone. This problem, involving the internal degrees of freedom of amino acid side-chains, significantly influences the protein's overall structure and function. In this work, we develop a resource-efficie…

Shallow-depth GHZ state generation on NISQ devices
In this work, we focus on GHZ state generation under the practical constraint of limited qubit connectivity, a hallmark of current NISQ hardware. We study the GHZ state preparation across different connectivity graphs inspired by IBM and Google chip architectures, as well as random graphs that reflect distributed quantum systems. Our approach is a measurement-based protocol designed to utilize qubit connectivity constraints for the generation of GHZ states on NISQ devices. We benchmark this aga…

Isoprobability Models of Qubit Dynamics: Demonstration via Time-Dependent Phase Control on IBM Quantum
Efficient quantum control is a cornerstone for the advancement of quantum technologies, from computation to sensing and communications. Several approaches in quantum control, e.g. optimal control and inverse engineering, use the pulse amplitude and frequency shaping as the control tools. Often, these approaches prescribe pulse shapes which are difficult or impossible to implement. To this end, we develop the concept of isoprobability classes of models of qubit dynamics, in which various pairs o…

Observation of Power Superbroadening of Spectral Line Profiles on IBM Quantum
Power broadening refers to the widening of the spectral line profile in a two-state quantum transition as the strength of the driving field increases. This phenomenon commonly arises in continuous-wave driving when the radiation field's intensity exceeds the transition's saturation intensity and it has been extensively studied in spectroscopy. For pulsed-field excitation, the spectral response of the quantum system may differ significantly: while a rectangular-shaped pulse leads to a linear pow…

Closing objectivity loophole in Bell tests on a public quantum computer
We have constructed and run a Bell test of local realism focusing on the objectivity criterion. The objectivity means that the outcomes are confirmed macroscopically by a few observers at each of party. The IBM Quantum devices turn out to be sufficiently accurate to pass such an extended Bell-type test, although at the price of communication loopholes and residual but statistically significant signaling. The test serves also as the benchmark of entanglement spread across larger sets of qubits.

Experimental Ground-State Energy of a 125-Site Flat Kagome Antiferromagnet via Hamiltonian Engineering on Quantum Computer
We present an instance of utility-grade quantum computation by calculating the ground-state energy of a 125-site flat Kagome lattice under the antiferromagnetic Heisenberg model (KAFH), using IBM's Falcon and Hummingbird quantum processors. For spin-1/2 KAFH, our best per-site ground-state energy estimate reaches -0.417J, and after applying open-boundary corrections, it closely approaches the established thermodynamic value of -0.438J. To achieve this, we propose a hybrid approach that splits t…
