Quantum 5, 400 (2021). https://doi.org/10.22331/q-2021-02-24-400 The Gottesman-Knill theorem states that a Clifford circuit acting on stabilizer states can be simulated efficiently on a classical computer. Recently, this result has been generalized to cover inputs that […]
Quantum 5, 399 (2021). https://doi.org/10.22331/q-2021-02-22-399 Simulating the dynamics and the non-equilibrium steady state of an open quantum system are hard computational tasks on conventional computers. For the simulation of the time evolution, several efficient quantum […]
Quantum 5, 398 (2021). https://doi.org/10.22331/q-2021-02-17-398 It has long been known that long-ranged entangled topological phases can be exploited to protect quantum information against unwanted local errors. Indeed, conditions for intrinsic topological order are reminiscent of […]
Quantum 5, 397 (2021). https://doi.org/10.22331/q-2021-02-15-397 Quantum communication technologies show great promise for applications ranging from the secure transmission of secret messages to distributed quantum computing. Due to fiber losses, long-distance quantum communication requires the use […]
Quantum 5, 396 (2021). https://doi.org/10.22331/q-2021-02-15-396 For universal quantum computation, a major challenge to overcome for practical implementation is the large amount of resources required for fault-tolerant quantum information processing. An important aspect is implementing arbitrary […]
