Quantum computing: past, present, future
Russel Love Theatre
Peter Hall Building
As extreme computer miniaturisation reaches into the realm where even stray atoms affect device performance, a new type of information processing paradigm is emerging – quantum computing. While we do not fully comprehend the strangeness of quantum mechanics (and possibly cannot), the idea that one can encode and process information in quantum versions of bits (qubits) has well and truly taken hold. After decades of fundamental theoretical and experimental research, programmable quantum computer devices are now emerging from research labs – the most advanced machines are now at the 50 qubit level and beyond. This is an exciting time. In the foreseeable future, we are likely to observe “quantum supremacy” (surpassing classical computing for specific problems), and a rush of development on the “quantum software” front to exploit the technology. In this talk I’ll review quantum computing, from qubit basics through to quantum error correction, the design challenges for full scale universal quantum computing, the sort of problems these machines could address, and the exciting developments happening here at the University in teaching and research.
