Quantum signatures of proper time in optical ion clocks
Gabriel Sorci, Joshua Foo, Dietrich Leibfried +2
Optical clocks based on atoms and ions probe relativistic effects with unprecedented sensitivity by resolving time dilation due to atom motion or different positions in the gravita…
Optimized experiment design and analysis for fully randomized benchmarking
Alex Kwiatkowski, Laurent J. Stephenson, Hannah M. Knaack +6
Randomized benchmarking (RB) is a widely used strategy to assess the quality of available quantum gates in a computational context. RB involves applying known random sequences of g…
Indirect Cooling of Weakly Coupled Trapped-Ion Mechanical Oscillators
Pan-Yu Hou, Jenny J. Wu, Stephen D. Erickson +6
Cooling the motion of trapped ions to near the quantum ground state is crucial for many applications in quantum information processing and quantum metrology. However, certain motio…
Experimental speedup of quantum dynamics through squeezing
S. C. Burd, H. M. Knaack, R. Srinivas +9
We show experimentally that a broad class of interactions involving quantum harmonic oscillators can be made stronger (amplified) using a unitary squeezing protocol. While our demo…
Trap-Integrated Superconducting Nanowire Single-Photon Detectors with Improved RF Tolerance for Trapped-Ion Qubit State Readout
Benedikt Hampel, Daniel H. Slichter, Dietrich Leibfried +3
State readout of trapped-ion qubits with trap-integrated detectors can address important challenges for scalable quantum computing, but the strong rf electric fields used for trapp…
Rotational spectroscopy of a single molecular ion at sub part-per-trillion resolution
Alejandra L. Collopy, Julian Schmidt, Dietrich Leibfried +2
We use quantum-logic spectroscopy (QLS) and interrogate rotational transitions of a single CaH+ ion with a highly coherent frequency comb, achieving a fractional statistical uncert…
