For certain problems quantum resources can exponentially increase computing power, but these quantum resources are very fragile in practice. When a quantum system interacts with an external environment, it undergoes decoherence the loss of quantum correlation and relaxation the loss of energy and eventually all of the quantum information is lost. Here we show a general principle of using unitar...

Hydraulic microelectrode advancermade by David Hubel. David Hubel was a giant in our field, yet he waswarm, friendly, and humble in person. He and Torsten Wiesel, following in the footsteps of their mentor Steve Kuffler, discovered fundamental principles of information processing in the brain and fundamental principles of how the brain wires itself up. I think many people in the field see David...
