Impossibility of Classically Simulating One-Clean-Qubit Computation
Keisuke Fujii, Hirotada Kobayashi, Tomoyuki Morimae +3
Deterministic quantum computation with one quantum bit (DQC1) is a restricted model of quantum computing where the input state is the completely mixed state except for a single cle…
Classical Realization of Dispersion Cancellation by Time-Reversal Method
Kazuhisa Ogawa, Shuhei Tamate, Toshihiro Nakanishi +2
We propose a classical optical interferometry scheme that reproduces dispersion-insensitive Hong-Ou-Mandel interferograms. The interferometric scheme is derived from a systematic m…
Computational quantum-classical boundary of complex and noisy quantum systems
Keisuke Fujii, Shuhei Tamate
It is often said that the transition from quantum to classical worlds is caused by decoherence originated from an interaction between a system of interest and its surrounding envir…
