Deterministic loading and phase shaping of microwaves onto a single artificial atom
W. -J. Lin, Y. Lu, P. Y. Wen +12
Loading quantum information deterministically onto a quantum node is an important step towards a quantum network. Here, we demonstrate that coherent-state microwave photons, with a…
Efficient frequency conversion based on resonant four-wave mixing
Chin-Yao Cheng, Zi-Yu Liu, Pi-Sheng Hu +8
Efficient frequency conversion of photons has important applications in optical quantum technology because the frequency range suitable for photon manipulation and communication us…
Ultimate quantum limit for amplification: a single atom in front of a mirror
Emely Wiegand, Ping-Yi Wen, Per Delsing +2
We investigate three types of amplification processes for light fields coupling to an atom near the end of a one-dimensional semi-infinite waveguide. We consider two setups where a…
Quantum walk processes in quantum devices
Anandu Kalleri Madhu, Alexey A. Melnikov, Leonid E. Fedichkin +2
Simulation and programming of current quantum computers as Noisy Intermediate-Scale Quantum (NISQ) devices represent a hot topic at the border of current physical and information s…
Generation of sub-MHz and spectrally-bright biphotons from hot atomic vapors with a phase mismatch-free scheme
Chia-Yu Hsu, Yu-Sheng Wang, Jia-Mou Chen +11
We utilized the all-copropagating scheme, which maintains the phase-match condition, in the spontaneous four-wave mixing (SFWM) process to generate biphotons from a hot atomic vapo…
Mesoscopic quantum superposition states of weakly-coupled matter-wave solitons
Dmitriy Tsarev, Alexander Alodjants, The Vinh Ngo +1
The Josephson junctions (JJs) are at the heart of modern quantum technologies and metrology. In this work we establish quantum features of an atomic soliton Josephson junction (SJJ…
