Indistinguishability between quantum randomness and pseudo-randomness under efficiently calculable randomness measures

Toyohiro Tsurumaru, Tsubasa Ichikawa, Yosuke Takubo +3

We present a no-go theorem for the distinguishability between quantum random numbers (i.e., random numbers generated quantum mechanically) and pseudo-random numbers (i.e., random n…

A comprehensive survey on quantum computer usage: How many qubits are employed for what purposes?

Tsubasa Ichikawa, Hideaki Hakoshima, Koji Inui +18

Quantum computers (QCs), which work based on the law of quantum mechanics, are expected to be faster than classical computers in several computational tasks such as prime factoring…

Quantum statistical effect induced through conditioned post-processing procedures with unitary -designs

Hideaki Hakoshima, Tsubasa Ichikawa

We propose a few-body quantum phenomenon, which manifests itself through stochastic state preparations and measurements followed by a conditioned post-processing procedure. We show…

Bayesianism, Conditional Probability and Laplace Law of Succession in Quantum Mechanics

Tsubasa Ichikawa

We present a comparative study between classical probability and quantum probability from the Bayesian viewpoint, where probability is construed as our rational degree of belief on…

Born Rule and Logical Inference in Quantum Mechanics

Tsubasa Ichikawa

Logical inference leads to one of the major interpretations of probability theory called logical interpretation, in which the probability is seen as a measure of the plausibility o…

Multi-partite squash operation and its application to device-independent quantum key distribution

Toyohiro Tsurumaru, Tsubasa Ichikawa

The squash operation, or the squashing model, is a useful mathematical tool for proving the security of quantum key distribution systems using practical (i.e., non-ideal) detectors…
