Scaling up single-atom spin qubits in silicon

Andrea Morello, Centre for Quantum Computation & Communication Technology, University of New South Wales

The modern information era is built on silicon nanoelectronic devices. The future quantum information era might be built on silicon too, if we succeed in controlling the interactions between individual spins hosted in silicon nanostructures.

Spins in silicon constitute excellent solid-state qubits, because of the weak spin-orbit coupling and the possibility to remove nuclear spins from the environment through 28Si isotopic enrichment.

Colloquium: Sergey Bravyi

Complexity of quantum impurity models

Sergey Bravyi, IBM Research

I will discuss classical and quantum algorithms for simulation of quantum impurity models. Such models describe a bath of free fermions coupled to a small interacting subsystem called an impurity. Hamiltonians of this form were famously studied by Anderson, Kondo, Wilson and others in 1960s.

Constraint Propagation Games

Zhengfeng Ji, University of Technology, Sydney

Constraint propagation games are simple extended nonlocal games that are motivated by the propagation checking of quantum computation and have found powerful applications in the study of quantum proof systems recently. In this talk, we will introduce their definitions and basic properties, demonstrate their uses in larger games as building blocks, and illustrate the method that turns them into nonlocal games.

Characterizing drift qubits

Timothy Proctor, Sandia National Laboratories

It is essential to benchmark and characterize real-world qubits in order to understand whether they are of sufficient quality for quantum information tasks, and if they are not, so that they can be debugged. Many techniques are designed for qubits that stay constant in time, but in reality almost all qubits suffer from some form of time-dependence.

Efficient quantum memory in naturally trapped Rare-Earth ions

Mahmood Sabooni, IQC

The ability to map, store quantum states of light (e. g. single photon) to matter and later retrieve is one of the important building blocks of quantum information processing. Such a device is called a quantum memory for light.

Dimensionality-driven orthorhombic MoTe2 at room temperature.

Joey Zhong

We use a combination of Raman spectroscopy and transport measurements to study thin flakes of the type-II Weyl semimetal candidate MoTe2 protected from oxidation. In contrast to bulk crystals, which experience a phase transition from monoclinic to the inversion symmetry breaking, orthorhombic phase below ~250 K, we find that in moderately thin samples below 10 nm, a single orthorhombic phase exists up to and beyond room temperature.
