    • Continuous Variable Quantum Computing

      Classical computing is gradually reaching the limit of its capabilities with reasonable time scales and resources. Quantum computing promises to provide a way to utilise quantum resources such as entanglement to solve problems which are currently thought to be hard classically1.

      Quantum computing uses the quantum analogue to the bit, a qubit, as the basic unit of information. These are then manipulated and measured to act out algorithms. Measurement-based quantum computing simplifies this process by establishing a highly entangled resource known as a cluster state and measures the qubits which make up the cluster state in a chosen basis2. The measurement itself also enacts the desired gate. This eliminates the need for coherent control over individual qubits.

      Our research group specialises in continuous variable (CV) measurement-based quantum computing. This uses CV resources, such as the electromagnetic field of light, to prepare the initial cluster state3. This means that the cluster state is easier to prepare and measure than a qubit cluster state. Qubits are encoded in the CVs and algorithms are performed using the logical qubits by measurements made of the CV cluster state.

    • Relativistic Quantum Information

      Relativistic quantum information (RQI) aims to understand how general relativity and quantum information interact and influence each other.

      The two most relevant aspects RQI are (1) understanding how quantum information concepts — such as quantum teleportation — are modified when relativity is included in the picture and (2) what new phenomena emerge when considering quantum entanglement in a relativistic setting.

      QuRMIT's RQI research includes using analogue models of gravity as a toolkit for exploring aspects of relativistic quantum information and exloring the full implication of an information theoretical approach to understanding the microscopic nature of gravity.
