Nuclear spin quantum memory in silicon carbide

Polarizing Nuclear Spins in Silicon Carbide

Quantum computers and other quantum information processing (QIP) devices—such as simulators, sensors, and communication channels—hold the promise to deliver performances not attainable by classical systems. Unfortunately, the qubits used to store information are usually fragile and difficult to manipulate and engineer, thus forestalling advances in the field. Many qubit candidates suffer from s...

Silicon Carbide for Novel Quantum Technology Devices

Silicon carbide (SiC) has recently been investigated as an alternative material to host deep optically active defects suitable for optical and spin quantum bits. This material presents a unique opportunity to realise more advanced quantum-based devices and sensors than currently possible. We will summarise key results revealing the role that defects have played in enabling optical and spin quan...

Toward a Silicon - Based Nuclear - Spin Quantum Computer

quantum computing is to identify a system that can be scaled up to the number of qubits needed to execute nontrivial quantum algorithms. Peter Shor’s algorithm for finding the prime factors of numbers used in public-encryption systems (numbers that typically consist of more than a hundred digits) would likely require a quantum computer with several thousand qubits. Depending on the error correc...

Spin and photophysics of carbon-antisite vacancy defect in 4H silicon carbide: A potential quantum bit

Polytype control of spin qubits in silicon carbide

Crystal defects can confine isolated electronic spins and are promising candidates for solid-state quantum information. Alongside research focusing on nitrogen-vacancy centres in diamond, an alternative strategy seeks to identify new spin systems with an expanded set of technological capabilities, a materials-driven approach that could ultimately lead to 'designer' spins with tailored propertie...
