What is" topological" about topological quantum states? How many types of topological
quantum phases are there? What is a zero-energy Majorana mode, how can it be realized in …

We show how to obtain concrete constructions of homological quantum codes based on
tilings of 2-D surfaces with constant negative curvature (hyperbolic surfaces). This …

The standard description of quantum mechanics considers the time-evolution of isolated
quantum systems whose unitary dynamics are governed by the Schrödinger equation …

Using a circuit QED device, we demonstrate a simple qubit-measurement pulse shape that
yields fast ring-up and ring-down of the readout resonator regardless of the qubit state. The …
