A high fidelity light-shift gate for clock-state qubits
C. H. Baldwin, B. J. Bjork, M. Foss-Feig +7
To date, the highest fidelity quantum logic gates between two qubits have been achieved with variations on the geometric-phase gate in trapped ions, with the two leading variants b…
Eliminating Leakage Errors in Hyperfine Qubits
D. Hayes, D. Stack, B. Bjork +3
Population leakage outside the qubit subspace presents a particularly harmful source of error that cannot be handled by standard error correction methods. Using a trapped Y…
Cavity QED with tunneling: an application of adiabatic elimination in quantum trajectory theory
Charles Baldwin, Perry Rice
We model the evolution of a single atom in a cavity interacting with two lasers, one far off resonance which creates an optical potential lattice and one near resonance, which can…
Joint Quantum-State and Measurement Tomography with Incomplete Measurements
Adam C. Keith, Charles H. Baldwin, Scott Glancy +1
Estimation of quantum states and measurements is crucial for the implementation of quantum information protocols. The standard method for each is quantum tomography. However, quant…
Experimental study of optimal measurements for quantum state tomography
H. Sosa-Martinez, N. K. Lysne, C. H. Baldwin +3
Quantum tomography is a critically important tool to evaluate quantum hardware, making it essential to develop optimized measurement strategies that are both accurate and efficient…
Strictly-complete measurements for bounded-rank quantum-state tomography
Charles H. Baldwin, Ivan H. Deutsch, Amir Kalev
We consider the problem of quantum-state tomography under the assumption that the state is pure, and more generally that its rank is bounded by a given value . In this scenario…
