The Quantum Innovators in science and engineering workshop brings together the most promising young researchers in quantum physics and engineering. Guests are invited for a four-day conference aimed at exploring the frontier of our field.

In recent years, circuit quantum electrodynamics (QED) has seen considerable efforts towards protecting quantum information from unwanted sources of decoherence through quantum error correction. Independent of the implementation, this is based on encoding a logical qubit into a stable manifold within a larger Hilbert space, whose symmetries restrict the number of independent errors and make them detectable and correctable.

On Thursday, June 7 the Institute for Quantum Computing (IQC) and the Perimeter Institute for Theoretical Physics (PI) will participate in the one-day Many-body States and Dynamics Workshop.

The goal of the workshop is to  describe ongoing efforts to experimentally realize quantum many-body states and dynamics, and discuss interesting classes of states and dynamics that could be targeted.

The number theory of quantum information

Jon Yard, IQC

Abstract: Quantum-mechanical amplitudes and unitaries are typically expressed over the complex numbers. Because there is a continuum of complex numbers, classical computations of quantum systems generally utilize finite-precision approximations by rational numbers.

The resource theory of quantum coherence studies the off-diagonal elements of a density matrix in a distinguished basis, whereas the resource theory of purity studies all deviations from the maximally mixed state. We establish a direct connection between the two resource theories, by identifying purity as the maximal coherence, which is achievable by unitary operations. The states that saturate this maximum identify a universal family of maximally coherent mixed states.

The Creative Destruction Lab (CDL) is hosting a half-day symposium to discuss recent advances in Quantum Machine Learning, its near-term industry applications, and opportunities for commercialization with private financing as a technology startup.
