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…
To catch and reverse a quantum jump mid-flight
Z. K. Minev, S. O. Mundhada, S. Shankar +6
Quantum physics was invented to account for two fundamental features of measurement results -- their discreetness and randomness. Emblematic of these features is Bohr's idea of qua…
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…
Demonstrating Quantum Error Correction that Extends the Lifetime of Quantum Information
Nissim Ofek, Andrei Petrenko, Reinier Heeres +10
The remarkable discovery of Quantum Error Correction (QEC), which can overcome the errors experienced by a bit of quantum information (qubit), was a critical advance that gives hop…
