Hardware-Economic Manipulation of Dual-Type Yb Qubits
Y. -J. Yi, Y. -Y. Chen, Y. -H. Hou +10
The dual-type qubit scheme is an emerging method to suppress crosstalk errors in scalable trapped-ion quantum computation and quantum network. Here we report a hardware-economic wa…
Stretched Exponential Scaling of Parity-Restricted Energy Gaps in a Random Transverse-Field Ising Model
G. -X. Tang, J. -Z. Zhuang, L. -M. Duan +1
The success of a quantum annealing algorithm requires a polynomial scaling of the energy gap. Recently it was shown that a two-dimensional transverse-field Ising model on a square…
Long-time storage of a decoherence-free subspace logical qubit in a dual-type quantum memory
Y. L. Xu, L. Zhang, C. Zhang +14
A quantum memory is an essential element for quantum computation, quantum network and quantum metrology. Previously, a single-qubit quantum memory with a coherence time of about an…
Programmable Quantum Simulations of Spin Systems with Trapped Ions
C. Monroe, W. C. Campbell, L. -M. Duan +10
Laser-cooled and trapped atomic ions form an ideal standard for the simulation of interacting quantum spin models. Effective spins are represented by appropriate internal energy le…
