Quantum Jump was a 1970s British band, consisting of keyboard player and singer Rupert Hine, guitarist Mark Warner, bass player John G. Perry (then of Caravan) and drummer Trevor Morais (ex-The Peddlers).
Quantum Jump was formed in 1973 at Farmyard rehearsal studios. The idea for the name came from a conversation Hine had with an ex-Cambridge University friend and filmmaker, Anthony Stern. "He had told me about the relatively recent discovery at Cambridge of the manner in which an electron's energy increases and decreases... not linearly as had been long assumed, but in a discrete step, known as a "quantum". The term "quantum jump" (later to be commonly referred to as "quantum leap") was coined by the Cambridge team. I preferred "jump", as it had more of a "soul / funk" music connotation".
