Adaptive quantum metrology with large dynamic range using short one-axis twists
Tyler G. Thurtell, Akimasa Miyake
Phase estimation with potentially large phase values, i.e., with large dynamic range, has many applications in quantum metrology, for example to atomic clocks. A recently proposed…
Quantum contextuality with mixed states of 1D symmetry-protected topological order
Leroy Fagan, Akimasa Miyake
Bell theorems of many-body nonlocality and contextuality serve as a benchmark for proving quantum advantage in that a quantum computer outperforms a classical computer for a certai…
Macroproperties vs. Microstates in the Classical Simulation of Critical Phenomena in Quench Dynamics of 1D Ising Models
Anupam Mitra, Tameem Albash, Philip Daniel Blocher +4
We study the tractability of classically simulating critical phenomena in the quench dynamics of one-dimensional transverse field Ising models (TFIMs) using highly truncated matrix…
Hardness results for decoding the surface code with Pauli noise
Alex Fischer, Akimasa Miyake
Real quantum computers will be subject to complicated, qubit-dependent noise, instead of simple noise such as depolarizing noise with the same strength for all qubits. We can do qu…
