Batched high-rate logical operations for quantum LDPC codes
Qian Xu, Hengyun Zhou, Dolev Bluvstein +5
High-rate quantum LDPC (qLDPC) codes reduce memory overhead by densely packing many logical qubits into a single block of physical qubits. Here we extend this concept to high-rate…
The vast world of quantum advantage
Hsin-Yuan Huang, Soonwon Choi, Jarrod R. McClean +1
The quest to identify quantum advantages lies at the heart of quantum technology. While quantum devices promise extraordinary capabilities, from exponential computational speedups…
Digital quantum simulations of scattering in quantum field theories using W states
Roland C. Farrell, Nikita A. Zemlevskiy, Marc Illa +1
High-energy particle collisions can convert energy into matter through the inelastic production of new particles. Quantum computers are an ideal platform for simulating the out-of-…
Observable and computable entanglement in time
Alexey Milekhin, Zofia Adamska, John Preskill
We propose a novel family of entanglement measures for time-separated subsystems. Our definitions are applicable to any quantum system, continuous or discrete. To illustrate their…
Real-Time Scattering in Ising Field Theory using Matrix Product States
Raghav G. Jha, Ashley Milsted, Dominik Neuenfeld +2
We study scattering in Ising Field Theory (IFT) using matrix product states and the time-dependent variational principle. IFT is a one-parameter family of strongly coupled non-inte…
