State exchange with quantum side information
Yonghae Lee, Ryuji Takagi, Hayata Yamasaki +2
We consider a quantum communication task between two users Alice and Bob, in which Alice and Bob exchange their respective quantum information by means of local operations and clas…
Hybrid quantum linear equation algorithm and its experimental test on IBM Quantum Experience
Yonghae Lee, Jaewoo Joo, Soojoon Lee
We propose a hybrid quantum algorithm based on the Harrow-Hassidim-Lloyd (HHL) algorithm for solving a system of linear equations. In our hybrid scheme, a classical information fee…
Activation of quantum capacity of Gaussian channels
Youngrong Lim, Soojoon Lee
Quantum channels can be activated by a kind of channels whose quantum capacity is zero. This activation effect might be useful to overcome noise of channels by attaching other chan…
Correspondence between maximally entangled states in discrete and Gaussian regimes
Youngrong Lim, Jaewan Kim, Soojoon Lee +1
We study a general corresponding principle between discrete-variable quantum states and continuous-variable (especially, restricted on Gaussian) states via quantum purification met…
