Research
Foundational and applied investigations across four interconnected domains of Quantum Information Science.
Area 01
Quantum Information & Computation
Research Topics
Quantum information theory, quantum algorithms, computing architectures, computational complexity, fault-tolerance, error-correction, quantum thermodynamics, and quantum simulations.
Research Snapshot
Syndrome measurements in quantum error correction can be used for estimation of parameters of an error channel and for hypothesis testing to distinguish error channels. Together with machine learning and control algorithms, syndrome measurements allow for in-situ characterization of quantum devices with error correction.
Area 02
Quantum Control & Measurement
Research Topics
Coherent control, control on qudit systems, fundamental questions of optimal control and algorithms, quantum tomography, and weak measurement.
Research Snapshot
Optimal quantum control applied to the ground-state manifold in Cesium atoms achieves full control of quantum states in high-dimensional spaces for the generation, control, and measurement of qudits with high fidelity.
Area 03
Quantum Optics & Communication
Research Topics
Quantum optics, quantum communication, and measurements of optical states.
Research Snapshot
The interaction of light and atomic ensembles allows for the generation of entangled photons for transmitting quantum information, and transferring this entanglement between flying qubits and atoms working as atomic quantum memories — enabling quantum repeaters for long-distance quantum communication.
Area 04
Quantum Metrology
Research Topics
Continuous quantum measurement and spin squeezing, quantum tomography, weak measurements, and the informational foundation of quantum metrology.
Research Snapshot
Quantum states of light and matter increase measurement sensitivity. The collective spin state of atomic ensembles prepared by back action of the dispersive interaction with light provides states with a high degree of squeezing for quantum-enhanced metrology.
