Active interference suppression in frequency-division-multiplexed quantum gates via off-resonant microwave tones
Haruki Mitarai, Yukihiro Tadokoro, Hiroya Tanaka
The increasing number of control lines connecting quantum processors to external electronics constitutes a major bottleneck in the realization of large-scale quantum computers. Fre…
Orthogonal frequency-division multiplexing for simultaneous gate operations on multiple qubits via a shared control line
Haruki Mitarai, Yukihiro Tadokoro, Hiroya Tanaka
The increasing number of qubits in quantum processors necessitates a corresponding increase in the number of control lines between the processor, which is typically operated at cry…
Fabrication of oriented NV center arrays in diamond via femtosecond laser writing and reorientation
Kai Klink, Andrew Raj Kirkpatrick, Yukihiro Tadokoro +2
Nitrogen-vacancy (NV) centers in diamond are widely recognized as highly promising solid-state quantum sensors due to their long room temperature coherence times and atomic-scale s…
Weighted Stochastic Riccati Equations for Generalization of Linear Optimal Control
Yuji Ito, Kenji Fujimoto, Yukihiro Tadokoro
This paper presents weighted stochastic Riccati (WSR) equations for designing multiple types of optimal controllers for linear stochastic systems. The stochastic system matrices ar…
Nanomechanical system meets ultra-small, robust, and ultra-low-powered digital communication receiver
Keita Funayama, Hiroya Tanaka, Jun Hirotani +3
Nanomechanical systems offer a versatile platform for both fundamental science and industrial applications. Resonating vibration has been demonstrated to enable an ultrasensitive d…
Noise-induced switching from a symmetry-protected shallow metastable state
Yukihiro Tadokoro, Hiroya Tanaka, M. I. Dykman
We consider escape from a metastable state of a nonlinear oscillator driven close to triple its eigenfrequency. The oscillator can have three stable states of period-3 vibrations a…
Simple Design on Nanoscale Receivers Using CNT Cantilevers
Yuji Ito, Yukihiro Tadokoro
A nanoscale receiver utilizing the cantilever of a carbon nanotube has been developed to detect phase information included in transmitted signals. The existing receiver consists of…
Driven nonlinear nanomechanical resonators as digital signal detectors
Yukihiro Tadokoro, Hiroya Tanaka, M. I. Dykman
Because of their nonlinearity, vibrational modes of resonantly driven nanomechanical systems have coexisting stable states of forced vibrations in a certain range of the amplitude…
CiNCT: Compression and retrieval for massive vehicular trajectories via relative movement labeling
Satoshi Koide, Yukihiro Tadokoro, Chuan Xiao +1
In this paper, we present a compressed data structure for moving object trajectories in a road network, which are represented as sequences of road edges. Unlike existing compressio…
Self-Fulfilling Signal of an Endogenous State in Network Congestion Games
Tatsuya Iwase, Yukihiro Tadokoro, Daisuke Fukuda
We consider the problem of coordination via signaling in network congestion games to improve social welfare deteriorated by incomplete information about traffic flow. Traditional s…
Fluctuation spectra of weakly driven nonlinear systems
Yaxing Zhang, Yukihiro Tadokoro, M. I. Dykman
We show that in periodically driven systems, along with the delta-peak at the driving frequency, the spectral density of fluctuations displays extra features. These can be peaks or…
Singular probability distribution of shot-noise driven systems
Akihisa Ichiki, Yukihiro Tadokoro, M. I. Dykman
We study the stationary probability distribution of a system driven by shot noise. We find that, both in the overdamped and underdamped regime, the coordinate distribution displays…
