U of C researchers make quantum breakthrough
From Crain's Chicago Business: University of Chicago researchers say they’ve made a breakthrough that might help bring quantum computing closer to reality. Researchers achieved a record time for memory, or “coherence,” in quantum bits, or qubits, of more than 5 seconds. Scientists are trying to harness quantum mechanics for the next generation of computing. One of the challenges is that particles maintain their quantum states, and their ability to store information, only briefly. Read More

Researchers set record by preserving quantum states for more than 5 seconds
A team of researchers at Argonne National Laboratory and the University of Chicago achieved two breakthroughs to overcome common challenges for quantum systems. They were able to read out their qubit on demand and then keep the quantum state intact for over five seconds — a new record for this class of devices. Read More

The race to build a fault-tolerant superconducting quantum computer
From IEEE Spectrum: Amazon, Google, and IBM are all pursuing different strategies to reduce error rates. Q-NEXT collaborator Oskar Painter of Caltech and team find they can 'make cat qubits that are highly resistant to bit flip, where a qubit flips from one state to another, one of two main sources of error a superconducting qubit can have.'
