How single-photon nonlinearity is quenched with multiple quantum emitters: Quantum Zeno effect in collective interactions with -level atoms
Alexander N. Poddubny, Serge Rosenblum, Barak Dayan
Single-photon nonlinearity, namely the change in the response of the system as the result of the interaction with a single photon, is generally considered an inherent property of a…
Superconducting cavity qubit with tens of milliseconds single-photon coherence time
Ofir Milul, Barkay Guttel, Uri Goldblatt +7
Storing quantum information for an extended period of time is essential for running quantum algorithms with low errors. Currently, superconducting quantum memories have coherence t…
Path-Independent Quantum Gates with Noisy Ancilla
Wen-Long Ma, Mengzhen Zhang, Yat Wong +5
Ancilla systems are often indispensable to universal control of a nearly isolated quantum system. However, ancilla systems are typically more vulnerable to environmental noise, whi…
High-fidelity measurement of qubits encoded in multilevel superconducting circuits
Salvatore S. Elder, Christopher S. Wang, Philip Reinhold +7
Qubit measurements are central to quantum information processing. In the field of superconducting qubits, standard readout techniques are not only limited by the signal-to-noise ra…
Error-corrected gates on an encoded qubit
Philip Reinhold, Serge Rosenblum, Wen-Long Ma +3
To solve classically hard problems, quantum computers need to be resilient to the influence of noise and decoherence. In such a fault-tolerant quantum computer, noise-induced error…
Fault-tolerant detection of a quantum error
S. Rosenblum, P. Reinhold, M. Mirrahimi +3
A critical component of any quantum error-correcting scheme is detection of errors by using an ancilla system. However, errors occurring in the ancilla can propagate onto the logic…
