Quantum Journal Club: Extending the lifetime of a quantum bit with error correction in superconducting circuits
Abstract: Quantum error correction (QEC) can overcome the errors experienced by qubits1 and is therefore an essential component of a future quantum computer. To implement QEC, a qubit is redundantly ...

Small Unextendible Sets of MUBs
Abstract: In quantum information, Mutually Unbiased Bases (MUBs) correspond to sets of pairwise complementary observables. The maximal number of such bases in a system of dimension d is d+1, and cons...

Quantum Journal Club: Demonstration of a Coherent Electronic Spin Cluster in Diamond
Abstract: An obstacle for spin-based quantum sensors is magnetic noise due to proximal spins. However, a cluster of such spins can become an asset, if it can be controlled. Here, we polarize and read...
