Joint IQIM/AWS Seminar Series

Abstract: A quantum memory is a procedure to store quantum information in a way that is robust to local noise for some fixed time. I will discuss two lower bounds on the number of additional physical registers required for a quantum memory. For the first one, I will focus on the dependence on time and allow very general operations. For the second one, I will require the operations to be geometrically local and focus on the dependence on the desired logical error rate. An important feature of these bounds is that they hold even if error-free classical computation is allowed.

Based on joint works with Nouédyn Baspin, Alexander Müller-Hermes and Ala Shayeghi available at https://arxiv.org/abs/2202.00119 and https://arxiv.org/abs/2302.04317.
