Improving Metrology with Quantum Scrambling
Zeyang Li, Simone Colombo, Chi Shu +7
Quantum scrambling describes the spreading of local information into many degrees of freedom in quantum systems. This provides the conceptual connection among diverse phenomena ran…
Extreme Spin Squeezing via Optimized One-Axis Twisting and Rotations
Sebastian C. Carrasco, Michael H. Goerz, Zeyang Li +3
We propose a novel scheme for the generation of optimal squeezed states for Ramsey interferometry. The scheme consists of an alternating series of one-axis twisting pulses and rota…
Collective Spin-Light and Light-Mediated Spin-Spin Interactions in an Optical Cavity
Zeyang Li, Boris Braverman, Simone Colombo +6
The interaction between an atomic ensemble and a light mode in a high-finesse optical cavity can easily reach the strong-coupling regime, where quantum effects dominate. In this re…
Time-Reversal-Based Quantum Metrology with Many-Body Entangled States
Simone Colombo, Edwin Pedrozo-Peñafiel, Albert F. Adiyatullin +4
In quantum metrology, entanglement represents a valuable resource that can be used to overcome the Standard Quantum Limit (SQL) that bounds the precision of sensors that operate wi…
Entanglement-Enhanced Optical Atomic Clock
Edwin Pedrozo-Peñafiel, Simone Colombo, Chi Shu +8
State-of-the-art atomic clocks are based on the precise detection of the energy difference between two atomic levels, measured as a quantum phase accumulated in a given time interv…
Scalable Quantum Tomography with Fidelity Estimation
Jun Wang, Zhao-Yu Han, Song-Bo Wang +4
We propose a quantum tomography scheme for pure qudit systems which adopts random base measurements and generative learning methods, along with a built-in fidelity estimation appro…
