Demonstrating Quadratic Monte Carlo Speedup via Quantum Amplitude Estimation: Nuclear Engineering Examples

Jilang Miao, Miaomiao Jin, Akira Sone

We demonstrate quantum amplitude estimation (QAE) as a route to quadratic speedup for Monte Carlo-type expectation values in nuclear engineering. Using QPE-based QAE, we study two…

Harnessing Intrinsic Noise for Quantum Simulation of Open Quantum Systems

Sameer Dambal, Akira Sone, Yu Zhang

Simulating open quantum systems on quantum computers presents a fundamental challenge: open quantum dynamics are intrinsically nonunitary, whereas quantum computers operate through…

No-go theorem for environment-assisted invariance in non-unitary dynamics

Akira Sone, Akram Touil, Kenji Maeda +2

We elucidate the requirements for quantum operations that achieve environment-assisted invariance (envariance), a symmetry of entanglement. While envariance has traditionally been…

Conditional quantum thermometry -- enhancing precision by measuring less

Akira Sone, Diogo O. Soares-Pinto, Sebastian Deffner

Taking accurate measurements of the temperature of quantum systems is a challenging task. The mathematical peculiarities of quantum information make it virtually impossible to meas…
