Performance and structure of single-mode bosonic codes
Victor V. Albert, Kyungjoo Noh, Kasper Duivenvoorden +9
The early Gottesman, Kitaev, and Preskill (GKP) proposal for encoding a qubit in an oscillator has recently been followed by cat- and binomial-code proposals. Numerically optimized…
Quantum Channel Construction with Circuit Quantum Electrodynamics
Chao Shen, Kyungjoo Noh, Victor V. Albert +5
Quantum channels can describe all transformations allowed by quantum mechanics. We provide an explicit universal protocol to construct all possible quantum channels, using a single…
Optimized Tomography of Continuous Variable Systems Using Excitation Counting
Chao Shen, Reinier W. Heeres, Phil Reinhold +4
We propose a systematic procedure to optimize quantum state tomography protocols for continuous variable systems based on excitation counting preceded by a displacement operation.…
Universal Control of an Oscillator with Dispersive Coupling to a Qubit
Stefan Krastanov, Victor V. Albert, Chao Shen +5
We investigate quantum control of an oscillator mode off-resonantly coupled to an ancillary qubit. In the strong dispersive regime, we may drive the qubit conditioned on number sta…
Holonomic quantum control with continuous variable systems
Victor V. Albert, Chi Shu, Stefan Krastanov +7
Universal computation of a quantum system consisting of superpositions of well-separated coherent states of multiple harmonic oscillators can be achieved by three families of adiab…
High Fidelity Quantum Gates for Trapped Ions under Micromotion
Chao Shen, Luming Duan
Two or three dimensional Paul traps can confine a large number of ions forming a Wigner crystal, which would provide an ideal architecture for scalable quantum computation except f…
Hopf Insulators and Their Topologically Protected Surface States
Dong-Ling Deng, Sheng-Tao Wang, Chao Shen +1
Three-dimensional (3D) topological insulators in general need to be protected by certain kinds of symmetries other than the presumed charge conservation. A peculiar exceptio…
Individual Addressing in Quantum Computation through Spatial Refocusing
Chao Shen, Zhe-xuan Gong, Luming Duan
Separate addressing of individual qubits is a challenging requirement for scalable quantum computation, and crosstalk between operations on neighboring qubits remains as a signific…
Efficient Spin Squeezing with Optimized Pulse Sequences
Chao Shen, Luming Duan
Spin squeezed states are a class of entangled states of spins that have practical applications to precision measurements. In recent years spin squeezing with one-axis twisting (OAT…
Quantum quench dynamics of the Bose-Hubbard model at finite temperatures
J. M. Zhang, C. Shen, W. M. Liu
We study quench dynamics of the Bose-Hubbard model by exact diagonalization. Initially the system is at thermal equilibrium and of a finite temperature. The system is then quenched…
Strong thermalization of the two-component Bose-Hubbard model at finite temperatures
J. M. Zhang, C. Shen, W. M. Liu
We study thermalization of a two-component Bose-Hubbard model by exact diagonalization. Initially the two components do not interact and are each at equilibrium but with different…
