Diamond Nanophotonics
Diamond is an excellent host material for long-lived spin qubits with optical transitions. The silicon vacancy color center is an atom-like defect which exhibits a bright and narrow optical transition and a long-lived ground state spin. Using nanophotonic devices we develop efficient interfaces to photonic qubits, which can be used to network numerous quantum processors.
Microphotonic Network Interfaces
Quantum processors with high qubit densities fundamentally have a size limit, similar to conventional processors. To build (quantum) super computers, we need to develop interfaces between state of the art computing platforms and photonic interconnects. Here we develop low-noise fiber resonators, compatible with atomic quantum computing systems.
Quantum-based Cryptography
Asymmetric cryptography relies on the assumption that certain mathematical problems are hard to solve, although all necessary information is provided in a public key. Quantum cryptography, on the other hand, can be information theoretically secure, meaning that no outside person can have information about the key material. We work on methods to efficiently utilize quantum key distribution to enable quantum-based cryptography.
