Power of one non-clean qubit
Tomoyuki Morimae, Keisuke Fujii, Harumichi Nishimura
The one-clean qubit model (or the DQC1 model) is a restricted model of quantum computing where only a single qubit of the initial state is pure and others are maximally mixed. Alth…
Verifiable fault-tolerance in measurement-based quantum computation
Keisuke Fujii, Masahito Hayashi
Quantum systems, in general, output data that cannot be simulated efficiently by a classical computer, and hence is useful for solving certain mathematical problems and simulating…
Hybrid quantum magnetic field sensor with an electron spin and a nuclear spin in diamond
Yuichiro Matsuzaki, Takaaki Shimooka, Hirotaka Tanaka +3
Recently, magnetic field sensors based on an electron spin of a nitrogen vacancy (NV) center in diamond have been studied both from an experimental and theoretical point of view. T…
Fault-tolerant verifiable blind quantum computing with logical state remote preparation
Yuki Takeuchi, Keisuke Fujii, Tomoyuki Morimae +1
Verifiable blind quantum computing allows a client with poor quantum devices to delegate universal quantum computing to a remote quantum server in such a way that the client's priv…
A 16-bit Coherent Ising Machine for One-Dimensional Ring and Cubic Graph Problems
Kenta Takata, Alireza Marandi, Ryan Hamerly +6
Many tasks in our modern life, such as planning an efficient travel, image processing and optimizing integrated circuit design, are modeled as complex combinatorial optimization pr…
Direct measurement of the optical trap-induced decoherence
Nobuyuki Matsumoto, Kentaro Komori, Sosuke Ito +2
Thermal decoherence is a major obstacle to the realization of quantum coherence for massive mechanical oscillators. Although optical trapping has been used to reduce the thermal de…
