Power of sequential protocols in hidden quantum channel discrimination
Sho Sugiura, Arkopal Dutt, William J. Munro +2
In many natural and engineered systems, unknown quantum channels act on a subsystem that cannot be directly controlled and measured, but is instead learned through a controllable s…
Minimum Trotterization Formulas for a Time-Dependent Hamiltonian
Tatsuhiko N. Ikeda, Asir Abrar, Isaac L. Chuang +1
When a time propagator for duration consists of two noncommuting parts , Trotterization approximately decomposes the propagator into a product of exponential…
Error-Robust Quantum Signal Processing using Rydberg Atoms
Sina Zeytinoğlu, Sho Sugiura
Rydberg atom arrays have recently emerged as one of the most promising platforms for quantum simulation and quantum information processing. However, as is the case for other experi…
Quantum advantage for noisy channel discrimination
Zane M. Rossi, Jeffery Yu, Isaac L. Chuang +1
Many quantum mechanical experiments can be viewed as multi-round interactive protocols between known quantum circuits and an unknown quantum process. Fully quantum "coherent" acces…
Adiabatic landscape and optimal paths in ergodic systems
Sho Sugiura, Pieter W. Claeys, Anatoly Dymarsky +1
Whether one is interested in quantum state preparation or in the design of efficient heat engines, adiabatic (reversible) transformations play a pivotal role in minimizing computat…
Many-body scar state intrinsic to periodically driven system: Rigorous results
Sho Sugiura, Tomotaka Kuwahara, Keiji Saito
The violation of the Floquet version of eigenstate thermalization hypothesis is systematically discussed with realistic Hamiltonians. Our model is based on the PXP type interaction…
Resonantly enhanced polariton wave mixing and Floquet parametric instability
Sho Sugiura, Eugene A. Demler, Mikhail Lukin +1
We introduce a new theoretical approach for analyzing pump and probe experiments in non-linear acousto-optic systems. In our approach, the effect of coherently pumped polaritons is…
Thermodynamical path integral and emergent symmetry
Shin-ichi Sasa, Sho Sugiura, Yuki Yokokura
We investigate a thermally isolated quantum many-body system with an external control represented by a step protocol of a parameter. The propagator at each step of the parameter ch…
Page Curves for General Interacting Systems
Hiroyuki Fujita, Yuya O. Nakagawa, Sho Sugiura +1
We calculate in detail the Renyi entanglement entropies of cTPQ states as a function of subsystem volume, filling the details of our prior work [Nature Communications 9, 1635 (2018…
Construction of Hamiltonians by supervised learning of energy and entanglement spectra
Hiroyuki Fujita, Yuya O. Nakagawa, Sho Sugiura +1
Correlated many-body problems ubiquitously appear in various fields of physics such as condensed matter physics, nuclear physics, and statistical physics. However, due to the inter…
Universality in volume law entanglement of pure quantum states
Yuya O. Nakagawa, Masataka Watanabe, Hiroyuki Fujita +1
A pure quantum state can fully describe thermal equilibrium as long as one focuses on local observables. Thermodynamic entropy can also be recovered as the entanglement entropy of…
Thermal pure state path integral and emergent symmetry
Shin-ichi Sasa, Sho Sugiura, Yuki Yokokura
We investigate a thermally isolated quantum many-body system with an external control represented by a time-dependent parameter. We formulate a path integral in terms of thermal pu…
Thermal Pure Quantum States of Many-Particle Systems
Masahiko Hyuga, Sho Sugiura, Kazumitsu Sakai +1
We generalize the thermal pure quantum (TPQ) formulation of statistical mechanics, in such a way that it is applicable to systems whose Hilbert space is infinite dimensional. Assum…
New Formulation of Statistical Mechanics using Thermal Pure Quantum States
Sho Sugiura, Akira Shimizu
We formulate statistical mechanics based on a pure quantum state, which we call a ``thermal pure quantum (TPQ) state''. A single TPQ state gives not only equilibrium values of mech…
Canonical Thermal Pure Quantum State
Sho Sugiura, Akira Shimizu
A thermal equilibrium state of a quantum many-body system can be represented by a typical pure state, which we call a thermal pure quantum (TPQ) state. We construct the canonical T…
Thermal Pure Quantum States at Finite Temperature
Sho Sugiura, Akira Shimizu
An equilibrium state can be represented by a pure quantum state, which we call a thermal pure quantum (TPQ) state. We propose a new TPQ state and a simple method of obtaining it. A…
