Quantum Error Correction and Dynamical Decoupling: Better Together or Apart?
Victor Kasatkin, Mario Morford-Oberst, Arian Vezvaee +1
Quantum error correction/detection (QEC/QED) and dynamical decoupling (DD) are tools for protecting quantum information. A natural goal is to combine them to outperform either appr…
Analog-Digital Quantum Computing with Quantum Annealing Processors
Rahul Deshpande, Majid Kheirkhah, Chris Rich +12
Quantum annealing processors typically control qubits in unison, attenuating quantum fluctuations uniformly until the applied system Hamiltonian is diagonal in the computational ba…
Universal Weakly Fault-Tolerant Quantum Computation via Code Switching in the [[8,3,2]] Code
Shixin Wu, Dawei Zhong, Todd A. Brun +1
Code-switching offers a route to universal, fault-tolerant quantum computation by circumventing the limitation implied by the Eastin-Knill theorem against a universal transversal g…
Decoherence of a tunable capacitively shunted flux qubit
R. Trappen, X. Dai, M. A. Yurtalan +19
Quantum annealing is a method to solve optimization problems that leverages quantum tunneling in a coupled qubit system. We present a detailed study of the coherence of a tunable c…
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…
Families of 2D subsystem stabilizer codes for universal Hamiltonian quantum computation with two-body interactions
Phattharaporn Singkanipa, Zihan Xia, Daniel A. Lidar
In the absence of fault tolerant quantum error correction for analog, Hamiltonian quantum computation, error suppression via energy penalties is an effective alternative. We constr…
