Problem-Specific Basis Quantum State Readout via Proper Orthogonal Decomposition
Kota Ichiki, Xinchi Huang, Gekko Budiutama +7
Quantum computing is a promising technology for accelerating partial differential equation solvers applied to large-scale real-world problems. However, reconstructing a classical r…
Analytical construction of quantum random access codes saturating the conjectured bound
Takayuki Suzuki
Quantum Random Access Codes (QRACs) embody the fundamental trade-off between the compressibility of information into limited quantum resources and the accessibility of that informa…
Optimal Control in Nearly-Adiabatic Two-Level Quantum Systems via Time-Dependent Resonance
Takayuki Suzuki
In this study, we theoretically analyzed a control protocol based on ``time-dependent resonance" in nearly adiabatic two-level quantum systems, demonstrating that it exhibits prope…
Analytical derivation and extension of the anti-Kibble-Zurek scaling in the transverse field Ising model
Kaito Iwamura, Takayuki Suzuki
A defect density which quantifies the deviation from the spin ground state characterizes non-equilibrium dynamics during phase transitions. The widely recognized Kibble-Zurek scali…
CP conditions for GKSL-like master equations
Akane Watanabe, Takayuki Suzuki, Makoto Unoki +1
The complete positivity (CP) of a quantum dynamical map (QDM) is, in general, difficult to show when its master equation (ME) does not conform to the Gorini-Kossakowski-Sudarshan-L…
