Project description
Quantum information processing counting on diamond defects
Quantum information processing promises to drastically increase the computation efficiency of problems that today’s conventional computers can handle with difficulty. It harnesses the power of quantum mechanics that encodes 0s and 1s in qubits. Funded under the Marie Skłodowska-Curie programme, the COHESiV project aims to leverage the remarkable optical, mechanical and spin coherence properties of a novel qubit, the silicon-vacancy centre in diamond, and establish it as a central quantum network component for implementing quantum information processing. The focus will be on entangling two quantum bits efficiently and storing quantum information in a long-lived quantum register.
Objective
The proposal COHESiV aims to establish a novel physical system with ideal properties for the realisation of quantum networks. Quantum information processing (QIP) promises to drastically increase computation abilities and thus unlock key computational problems with wide ranging benefits. An outstanding issue is however the choice of the fundamental building block to implement QIP. COHESiV's goal is to take advantage of the remarkable optical, mechanical and spin coherence properties of a novel quantum bit, the silicon-vacancy centre (SiV) in diamond and establish it as a central component of quantum networks for the implementation of QIP. To do so, COHESiV addresses two crucial operations on which standard quantum algorithms are based: entangling two quantum bits efficiently and storing quantum information in a long-lived quantum register. COHESiV’s objectives are to 1) Interface the spin of a single SiV with a well-defined vibrational mode (phonon) of a mechanical resonator 2) Demonstrate phonon-mediated entanglement between two SiV spins 3) Take advantage of long-lived neighbouring nuclear spins to store and retrieve a quantum state encoded in the SiV spin. Owing to the fact that the strong coupling regime between spin and phonon will be attainable with current mechanical resonators thanks to the remarkably large strain susceptibility of the SiV spin, COHESiV will also aim to open the new field of quantum acousto-dynamics, analogous to quantum electrodynamics, where phonons replace photons. Those objectives will be achieved by combining the expertise of the researcher on the physics of the SiV centre with the state-of-the-art design and fabrication of diamond nanostructures of the outgoing phase partner and the breakthroughs in QIP with a comparable physical system at the host institution.
