Department of Physics, School of Natural Sciences organizes a seminar: Quantum Condensed Matter Meets Quantum Computing
We offer a perspective on quantum information storage and quantum error correction through the lens of quantum many-body systems. We shall begin by examining a toy model of a topological superconductor with Majorana excitations and show that it could serve as a viable candidate for producing topologically protected quantum qubits. Next, we shall present the concept of frustration-free spin Hamiltonians and establish the link between their ground states and quantum error-correcting codes. We shall conclude by demonstrating such an error-correcting code in action.
