Quantum Computing

Quantum computers will be able to solve certain 'multi-root' problems (e.g. factorising very large numbers) much more quickly than any classical computers that use even the best algorithms. Oxford Instruments' wide range of systems provides the low temperature environment that is essential to the performance of the quantum processor. This processor is able to address complex computational challenges that are difficult or impractical to perform using conventional systems, and represents a paradigm shift in quantum technology.

Quantum Information Processing

In a world overwhelmed by increasing amount of data, finding new ways to store and process information has become a necessity. Quantum information processing (QIP) uses qubits as its basic information units. QIP has many facets - from quantum simulation, to cryptography, to quantum computation, which is expected to solve problems more complex than those within the capabilities of conventional computers.

Quantum Hall

The quantum Hall effect is a quantum-mechanical version of the Hall effect, observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields. Physicists have long used standard electrical transport measurements such as resistivity, conductance and the Hall effect to gain information on the electronic properties and structure of materials. Now quantum transport measurements such as the quantum Hall effect (QHE) and fractional quantum Hall effect (FQHE) in two-dimensional electron gases (2DEG) and topological insulators – along with a range of other more complex measurements – inform researchers on material properties with ultimate precision leading to primary standards

Quantum Sensing

The discoveries and development of quantum physics in the early 20th century transformed science and unlocked whole new generations of innovative and commercial technologies. Quantum technologies now carry the promise of enabling the next generation of sensors and detectors which exploit quantum effects. Many quantum technologies will rely upon ultra low temperatures (close to absolute zero) to work. Our user-friendly ultra low temperature environments make this possible. Quantum sensing describes the use of a quantum system, quantum properties or quantum phenomena to perform a measurement of a physical quantity. The field is expected to provide new opportunities especially with regard to high sensitivity and precision in applied physics and other areas of science.

Quantum Transport Measurements

Quantum transport measurements are widely used in characterising new materials and devices for emerging quantum technology applications such as quantum information processing (QIP), quantum computing (QC) and quantum sensing. Such devices hold the potential to revolutionise future technology in high performance computing and sensing in the same way that semiconductors and the transistor did over half a century ago.

Transport properties of low dimensional semiconductors

Join Javad Shabani, Assistant Professor of Physics at New York University and a member of the Centre for Quantum Phenomena and Dr Gustav Teleberg, Cryogenics Product Specialist at Oxford Instruments

Near surface quantum wells with strong spin orbit coupling have attracted a great deal of interest since they can be interfaced epitaxially with superconducting films and have proved as a robust platform for exploring mesoscopic and topological superconductivity. In this work, Dr Shabani uses an Oxford Instruments’ 12 Tesla TeslatronPT top loader superconducting magnet system to study transport properties of quantum wells, quantum Hall effect, Shubnikov de Haas mass measurements and spin orbit coupling in these two-dimensional gas systems.
