From quantum speed limits to energy-efficient quantum gates

Understand

While recent breakthroughs in quantum computing promise the nascence of the quantum information age, quantum states remain delicate to control.

• Moreover, the required energy budget for large scale quantum applications has only sparely been considered.
• Addressing either of these issues necessitates a careful study of the most energetically efficient implementation of elementary quantum operations.
• In the present analysis, we show that this optimal control problem can be solved within the powerful framework of quantum speed limits.
