What we do
Quantum Computation
Quantum information can be encoded over various matter-based or light-based physical platforms. Quantum bits, or qubits, when protected using quantum error correction and processed fault tolerantly using universal logic gate sets, can be used to execute quantum algorithms that can provide super-polynomial speedups in solving certain classes of computational problems.
Quantum Communications & Networking
Special purpose quantum computers known as quantum repeaters along with optical links and switches in tandem with cleverly designed network protocols can enable high rate, reliable logical connectivity between quantum nodes in a network. Applications include secure classical communications, secure delegated cloud quantum computation, and scalable modular quantum computing architectures.
Quantum Sensing
Novel quantum optical and matter-based interferometric sensors that use non-classical, entangled probe states and non-standard detection schemes can beat the classical shot-noise limit and attain quantum-limited precisions. Applications lie in gravitational astronomy, target detection and ranging, microscopy, magnetometry, and atomic clocks.
