THE NEED FOR QUANTUM SOFTWARE
Recent years have witnessed spectacular breakthroughs in the development of quantum computers.
In 2014, the UC Santa Barbara group led by John Martinis (now part of Google’s Quantum Artificial
Intelligence Lab) created a high-performance 9-qubit platform. Subsequently they programmed it to
do the first-ever digital quantum simulation of a theoretical physics problem. Several groups are currently close to realizing quantum computers on 50 qubits.
The chart below shows the projected growth in the number of qubits in a quantum computer as projected at the start of QuSoft (though current developments are even faster than projected). It is based on the UCSB/Google developments sketched above, as well as progress on few-qubit platforms made at other labs using a variety of approaches.
