Here, using a quantum processor with five superconducting qubits, the authors demonstrate how to protect one logical qubit from bitflip errors using multi-qubit, stabilizer measurements.

Happy Pi Day! Here's how you can empirically determine the value of this well-known mathematical constant.

Pi can be calculated using a random sample of darts thrown at a square and circle target.

Calculating the value of pi has proved a headache for many a mathematician. Today, we leave it up to the computers, as well we should. It's a detailed and laborious process that can, and has ...
