We implement the DiVincenzo-Shor 5 qubit quantum error correcting code into a solid-state quantum register. The quantum register is a multi charge-qubit system in a semiconductor environment, where th...
The hydrogen molecule may be the simplest of all two-atom systems, but chemists have had to work very hard to calculate its properties from first principles using quantum mechanics. Now, however, a te...
