Demonstration of High-Fidelity Entangled Logical Qubits using Transmons
Arian Vezvaee, Vinay Tripathi, Mario Morford-Oberst +3
Quantum error correction (QEC) codes are necessary to fault-tolerantly operate quantum computers. However, every such code is inherently limited by its inability to detect logical…
Real-time Sign-Problem-Suppressed Quantum Monte Carlo Algorithm For Noisy Quantum Circuit Simulations
Tong Shen, Daniel A. Lidar
We present a real-time quantum Monte Carlo algorithm that simulates the dynamics of open quantum systems by stochastically compressing and evolving the density matrix under both Ma…
Beating the Ramsey limit on sensing with deterministic qubit control
M. O. Hecht, Kumar Saurav, Evangelos Vlachos +2
Quantum sensors promise revolutionary advances in medical imaging, energy production, mass detection, geodesy, foundational physics research, and a host of other fields. In many se…
Efficient Chromatic-Number-Based Multi-Qubit Decoherence and Crosstalk Suppression
Amy F. Brown, Daniel A. Lidar
The performance of quantum computers is hindered by decoherence and crosstalk, which cause errors and limit the ability to perform long computations. Dynamical decoupling is a tech…
