A quantum algorithm for obtaining the lowest eigenstate of a Hamiltonian assisted with an ancillary qubit system
Jeongho Bang, Seung-Woo Lee, Chang-Woo Lee +1
We propose a quantum algorithm to obtain the lowest eigenstate of any Hamiltonian simulated by a quantum computer. The proposed algorithm begins with an arbitrary initial state of…
Quantum tele-amplification with a continuous variable superposition state
Jonas S. Neergaard-Nielsen, Yujiro Eto, Chang-Woo Lee +2
Optical coherent states are classical light fields with high purity, and are essential carriers of information in optical networks. If these states could be controlled in the quant…
Generating a Schrödinger-cat-like state via a coherent superposition of photonic operations
Chang-Woo Lee, Jinhyoung Lee, Hyunchul Nha +1
We propose an optical scheme to generate a superposition of coherent states with enhanced size adopting an interferometric setting at the single-photon level currently available in…
