Quantum computing and qubit scale-up applications with Proteox
In this webinar James Robinson provides an overview of the new Proteox dilution refrigerator from Oxford Instruments, highlighting the key features and suitability for many quantum computing and qubit scale-up applications.
Transport properties of low dimensional semiconductors
Find out how Javad Shabani uses a 12 Tesla Teslatron top loader system to study transport properties of such quantum wells, quantum Hall effect, Shubnikov de Haas mass measurements and spin orbit coupling in these two dimensional gas systems.
Cryofree magnet system for low temperature transport measurement
Mengqiao has been working with Oxford Instruments Nanoscience for 5 years. He obtained his Ph.D. in condensed matter physics at Fudan University, China. His background is low temperature transport measurement of 2D materials.
Fractional conductance quantisation in one-dimensional electrons
In this webinar, Sanjeev will present results on the recently discovered zero-magnetic fractional conductance quantisation in quasi-one-dimensional electrons realized in GaAs/AlGaAs semiconductor heterostructures. The non-trivial characteristics and potential of these non-magnetic fractional states for future quantum technologies would be discussed.
Studying the flow of electrons in few-layer graphene
Two dimensional materials are of great interest for fundamental science and applications. There have been extensive studies on monolayer graphene where unique properties result from the symmetry of the honeycomb lattice. Few-layer graphene systems are of interest as they offer interesting opportunities to study effect of electronic interactions while monolayer graphene was largely understood in terms of independent electron picture.
Parametrically driven gates and loss operators in superconducting circuits
Third order nonlinearities have long been used to power parametrically-driven microwave amplifiers for measurement of superconducting qubits. I will present two new experiments which adapt the same parametric drives to control and couple transmon qubits and high-Q cavities. In both cases, the three-wave couplings in the system are created in a flux-biased, SNAIL-based resonator, which is dispersively coupled to the objects to be controlled.
