Last night we went to Timbl's interview at the #CheltLitFest on his memoir, This is for Everyone. It was both sad and evidence of courage with his devotion to openness in our little land of Web.
The book tour has evidently been exhausting. Whatever neurological event he's going through with the physical difficulty of speaking and his occasional aphasia, his brain is still ther…

Heute standen die Tempel und Schreine im Osten von #Kyoto auf dem Plan, die wir entlang des Waldrandes abgingen. Start war beim Kiyomizu-dera, der im Wald am Hang eingebettet schöne Blicke auf den Tempel selbst und die Stadt bietet.
Weiter ging es durch das noch historisch erhaltene Viertel Higashiyama, unter anderem zum Kodai-ji mit seinem schönen Garten und dem Chion-in.

Tunable magnon-phonon cavity via structural phase transition
Strong coupling between two quantized excitations in a cavity has the potential to lead to hybridized states that bestow novel quantum phenomena as required for emerging applications. In particular, tunable hybrid magnon-phonon cavities with precise control knobs are in pressing demand for developing quantum functionalities in solid-state platforms. Here, using a combination of synthesis and characterization tools, we present an epitaxial La0.7Sr0.3MnO3/SrTiO3 (LSMO/STO) heterostructure that ma…

ORAC: Disconnect. [The glasses tumble off the tray which begins to swoop around in the air.]
DAYNA: I don't believe that.
VILA: Try and convince me, will you? Please?

Gate-tunable Josephson parametric amplifiers based on semiconductor nanowires
Superconductor-semiconductor hybrid materials have been extensively used for experiments on electrically tunable quantum devices. Notably, Josephson junctions utilizing nanowire weak links have enabled a number of new gate-tunable qubits, including gatemons, Andreev level qubits and spin qubits. Conversely, superconducting parametric amplifiers based on Josephson junctions have not yet been implemented using nanowires, even though such nearly quantum limited amplifiers are key elements in exper…

Enabling full localization of qubits and gates with a multi-mode coupler
Tunable couplers are a key building block of superconducting quantum processors, enabling high on-off ratios for two-qubit entangling interactions. While crosstalk can be mitigated in idle mode, conventional single-mode couplers lack independent control over interactions in the one- and two-excitation manifolds, leading to unitary errors such as leakage during gate operations. Moreover, even at the nominal decoupled point, residual wavefunction delocalization persists, causing unintended qubit-…
