Equivariant learning of a transferable three-dimensional classical density functional
Bingqing Cheng
Liquids exhibit collective behavior that depends sensitively on thermodynamic conditions, interfaces and confinement, yet predicting each new state commonly requires a separate ato…
Bosonic Cyclic Codes: Trading Stabilizers for Gaussian Non-Clifford Phase Gates
Owen C. Wetherbee, Yijia Xu, Victor V. Albert +2
Bosonic codes offer hardware-efficient approaches to quantum error correction, with the best encodings offering effective protection of idle quantum information against loss and de…
Strain engineering of Andreev spin qubits in Germanium
Vittorio Coppini, Patrick Del Vecchio, Antonio L. R. Manesco +4
Planar germanium heterostructures are promising hosts for hybrid quantum devices due to their compatibility with superconductors, low material disorder, and relaxed fabrication con…
Quantum computational displacement sensing
Sridhar Prabhu, Saeed A. Khan, Xingrui Song +7
Quantum computational sensing (QCS) combines quantum sensing with quantum computing to extract task-relevant information from the physical world. QCS can in principle achieve an ac…
Error semitransparent universal control of a bosonic logical qubit
Saswata Roy, Owen C. Wetherbee, Valla Fatemi
Bosonic codes offer hardware-efficient approaches to logical qubit construction and hosted the first demonstration of beyond-break even logical quantum memory. However, such accomp…
Andreev spin qubits bound to Josephson vortices in spin-orbit coupled planar Josephson junctions
Katharina Laubscher, Valla Fatemi, Jay D. Sau
We propose a variant of Andreev spin qubits (ASQs) defined in planar Josephson junctions based on spin-orbit coupled two-dimensional electron gases (2DEGs) in a weak out-of-plane m…
