Magnetoelectric flat band induced by a charge density wave in monolayer CrSe
Pablo Savino, M. del Carmen Fuente Santiago, Jan Phillips +4
We investigate the electronic and magnetic properties of the polar charge-density-wave (CDW) phase of CrSe using ab initio calculations. The CDW introd…
Loopless multiterminal quantum circuits at odd parity
Antonio Manesco, Anton Akhmerov, Valla Fatemi
We theoretically investigate loopless multiterminal hybrid superconducting devices at odd fermion parity with time-reversal symmetry. We find that the energy-phase relationship has…
Frozonium: Freezing Anharmonicity in Floquet Superconducting Circuits
Keiran Lewellen, Rohit Mukherjee, Haoyu Guo +3
Floquet engineering is a powerful method that can be used to modify the properties of interacting many-body Hamiltonians via the application of periodic time-dependent drives. Here…
A Mathematical Structure for Amplitude-Mixing Error-Transparent Gates for Binomial Codes
Owen C. Wetherbee, Saswata Roy, Baptiste Royer +1
Bosonic encodings of quantum information offer hardware-efficient, noise-biased approaches to quantum error correction relative to qubit register encodings. Implementations have fo…
Fast readout of quantum dot spin qubits via Andreev spins
Michèle Jakob, Katharina Laubscher, Patrick Del Vecchio +3
Spin qubits in semiconducting quantum dots are currently limited by slow readout processes, which are orders of magnitude slower than gate operations. In contrast, Andreev spin qub…
Full characterization of measurement-induced transitions of a superconducting qubit
Thomas Connolly, Pavel D. Kurilovich, Vladislav D. Kurilovich +12
Repeated quantum non-demolition measurement is a cornerstone of quantum error correction protocols. In superconducting qubits, the speed of dispersive state readout can be enhanced…
