Universal continuous-variable state orthogonalizer and qubit generator

AS Coelho, LS Costanzo, A Zavatta, C Hughes… - Physical Review Letters, 2016 - APS
We experimentally demonstrate a universal strategy for producing a quantum state that is
orthogonal to an arbitrary, infinite-dimensional, pure input one, even if only a limited amount …

Quantum Gram-Schmidt processes and their application to efficient state readout for quantum algorithms

K Zhang, MH Hsieh, L Liu, D Tao - Physical Review Research, 2021 - APS
Many quantum algorithms that claim speedup over their classical counterparts only
generates quantum states as solutions instead of their final classical description. The …

Induced States from Coherent State via Photon-Addition Operations

HC Yuan, XX Xu, JW Cai, YJ Xu, XG Meng - International Journal of …, 2019 - Springer
Three classes of quantum states are induced from coherent state (CS) based on three
operations associated with the photon creation operator. One class is the famous photon …

Faithful conditional quantum state transfer between weakly coupled qubits

M Miková, I Straka, M Mičuda, V Krčmarský, M Dušek… - Scientific Reports, 2016 - nature.com
One of the strengths of quantum information theory is that it can treat quantum states without
referring to their particular physical representation. In principle, quantum states can be …

Nonclassical properties of induced states from single-mode squeezed vacuum state related with Hermite excited elementary superposition operation

X Xu, J Wang, H Yuan, Y Xu, X Meng - The European Physical Journal …, 2019 - Springer
Based on single-mode squeezed vacuum state (SVS) and Hermite-excited elementary
superposition operator H_m(xa^\dagger+ya) H m (xa†+ ya), we induce two new quantum …

Nonclassical properties of coherent state orthogonalization via Hermite polynomial excited operation

HC Yuan, XX Xu, JW Cai, YJ Xu - Laser Physics Letters, 2019 - iopscience.iop.org
In this work, we theoretically construct an orthogonal state of a coherent state where the
orthogonalizer is based on the Hermite polynomial excited operation with H m (x) being a …

Orthogonalization of coherent state and generation of continuous-variable qubit state via a coherent superposition of photon addition and subtraction

JM Wang, XX Xu - Modern Physics Letters A, 2018 - World Scientific
Based on the coherent state (S1) and the operator (xa†+ ya) m, we induce other three
quantum states (here we abbreviate them as S2, S3 and S4). S2 is obtained by operating …

Heralded orthogonalisation of coherent states and their conversion to discrete-variable superpositions

R Kruse, C Silberhorn, T Bartley - Quantum Measurements and …, 2017 - degruyter.com
The nonorthogonality of coherent states is a fundamental property which prevents them from
being perfectly and deterministically discriminated. Here, we present an experimentally …

Single-mode squeezed vacuum state orthogonalization via photon-addition operation

HC Yuan, XX Xu, JW Cai, YJ Xu - Optik, 2019 - Elsevier
We construct some orthogonal states for single-mode squeezed vacuum state (SVS) and
study their nonclassicality by virtue of the quadrature squeezing and the Wigner function …
