Universal fast flux control of a coherent, low-frequency qubit
Helin Zhang, Srivatsan Chakram, Tanay Roy +6
The \textit{heavy-fluxonium} circuit is a promising building block for superconducting quantum processors due to its long relaxation and dephasing time at the half-flux frustration…
Error-Mitigated Quantum Gates Exceeding Physical Fidelities in a Trapped-Ion System
Shuaining Zhang, Yao Lu, Kuan Zhang +4
Various quantum applications can be reduced to estimating expectation values, which are inevitably deviated by operational and environmental errors. Although errors can be tackled…
Probing Quantum Fluctuations of Work with a Trapped Ion
Yao Lu, Shuoming An, Jing-Ning Zhang +1
In this chapter, we illustrate how a trapped ion system can be used for the experimental study of quantum thermodynamics, in particular, quantum fluctuation of work. As technology…
Scalable global entangling gates on arbitrary ion qubits
Yao Lu, Shuaining Zhang, Kuan Zhang +5
A quantum algorithm can be decomposed into a sequence consisting of single qubit and 2-qubit entangling gates. To optimize the decomposition and achieve more efficient construction…
Universal stabilization of single-qubit states using a tunable coupler
Ziwen Huang, Yao Lu, Eliot Kapit +2
We theoretically analyze a scheme for fast stabilization of arbitrary qubit states with high fidelities, extending a protocol recently demonstrated experimentally [Lu et al., Phys.…
Universal stabilization of a parametrically coupled qubit
Yao Lu, Srivatsan Chakram, Nelson Leung +7
We autonomously stabilize arbitrary states of a qubit through parametric modulation of the coupling between a fixed frequency qubit and resonator. The coupling modulation is achiev…
