Research objectives
PQS2D is broken down into three thrusts, each with its own goals leading towards the creation of programmable quantum simulators.
Thrust 1
Moiré heterostructures as quantum simulators
Led by Dr. Adam Wei Tsen
In this thrust we aim to expand the range of engineered lattice structures and their symmetries by considering 1D systems, twisted magnets, charge density waves and their heterostructures. These lattice structures will be probed electrically, by local probes as well as optically.
Our objectives for this thrust include the experimental implementation of moiré simulators as well as the development of moiré systems theory.
Thrust 2
Gated quantum dots as quantum simulators
Led by Dr. Louis Gaudreau
In this thrust we will focus on implementing quantum simulators based on gate-defined quantum dots (atomistic and electrostatically defined). We will explore the few carrier regime of a gated quantum dots, multiple quantum dots, as well as the nature of intrinsic atomic defects in 2D materials and their deterministically position 2D defects.
To advance from a defect to a device, we will use a novel nanolithography technique. On the theory side, we will develop a set of novel predictive, computational tools describing quantum simulators.
Thrust 3
Large-area high-purity 2D materials synthesis
Led by Dr. James Gupta
In this thrust we produce 2D materials on wafer scale. Our consortium is among few in the world with the critical infrastructure and growth expertise necessary to engineer the 2D material properties on the atomic scale. We will achieve the required material properties using established semiconductor technologies on wafer scale adapted to the new challenges.
We will also explore novel techniques to manipulate the 2D layers from the wafer onto desired substrates for further processing into quantum simulator devices.
