Artistic presentation on how we could engineer and operate a powerful silicon quantum computer. A silicon chip is equipped with large ordered arrays of donor atoms. An upgraded semiconductor industry process - called 'Single Ion Implantation' - is the key to make this possible. In this example, we create pairs of antimony atoms at each node in the array. These antimony pairs can be used to realise many high-quality spin qubits that feature easier control and other fantastic properties to reduce the complexity of a quantum processor chip.

“Atomic gases have been a proving ground for high performance quantum memories at CQC2T. It’s a medium that allows for the rapid development and precise testing of quantum memory and related atom light protocols this is because the properties of the atomic ensembles are determined how we trap the gas meaning the ensembles can be tuned and modified on demand.”
Associate Professor Matthew Sellars
Program Manager, Rare-Earth Integration
Australia National University
“At CQC2T we’re developing a memory platform which will readily interface with optical communication channels. This memory will have storage time, data storage capacity and fidelity to make it suitable for network applications. To achieve this the Centre is working on two complementary approaches: atomic gases and solid state.”

Abstract:
Fermionic Linear Optics (FLO) is a restricted model of quantum computation which in its original form is known to be efficiently classically simulable. We show that, when initialized with suitable input states, FLO circuits can be used to demonstrate quantum computational advantage with strong hardness guarantees. Based on this, we propose a quantum advantage scheme which is a fermionic analogue of Boson Sampling: Fermion Sampling with magic input states.
We consider in parallel two classes of circuits: particle-number conserving (passive) FLO and active FLO that preserves only fermionic parity and is closely related to Matchgate circuits introduced by Valiant. Mathematically, these classes of circuits can be understood as fermionic representations of the Lie groups U(d) and SO(2d). This observation allows us to prove our main technical results. We first show anticoncentration for probabilities in random FLO circuits of both kind. Moreover, we prove robust average-case hardness of computation of probabilities. To achieve this, we adapt the worst-to-average-case reduction based on Cayley transform, introduced recently by Movassagh, to representations of low-dimensional Lie groups. Taken together, these findings provide hardness guarantees comparable to the paradigm of Random Circuit Sampling.

Title: Go big or go home: scaling up quantum computing with optical continuous-variable systems
Abstract: Quantum computers promise to revolutionise information processing by exploiting the curious features of quantum physics. One of the biggest challenges to a viable quantum computer with real-world impact is scaling it up to handle large computations. Optical modes can be stitched together into extremely large entangled resource states for quantum computing, comprising one million modes or more, if continuous variables are used instead of single photons. In this talk, I will introduce the principles of continuous-variable quantum computing and discuss recent theoretical and experimental results in this exciting field.
