(TechnologyNetworks) Dr Alexis Kirke, Senior Research Fellow in the Interdisciplinary Centre for Computer Music Research at the University of Plymouth (UK), has for the first time shown that a human musician can communicate directly with a quantum computer via teleportation.
The result is a high-tech jamming session, through which a blend of live human and computer-generated sounds come together to create a unique performance piece.
Dr Kirke said, “The world is racing to build the first practical and powerful quantum computers, and whoever succeeds first will have a scientific and military advantage because of the extreme computing power of these machines. This research shows for the first time that this much-vaunted advantage can also be helpful in the world of making and performing music. No other work has shown this previously in the arts, and it demonstrates that quantum power is something everyone can appreciate and enjoy.”
Quantum teleportation is the ability to instantaneously transmit quantum information over vast distances, with scientists having previously used it to send information from Earth to an orbiting satellite over 870 miles away.
In his current study, Dr Kirke describes how he used a system called MIq (Multi-Agent Interactive qgMuse), in which an IBM quantum computer executes a methodology called Grover’s Algorithm. It is significantly faster than any classical computer algorithm, and Dr Kirke said that speed was essential because there is actually no way to transmit quantum information other than through teleportation.
The result was that when played the theme from Game of Thrones on the piano, the computer – a 14-qubit machine housed at IBM in Melbourne – rapidly generated accompanying music that was transmitted back in response.
