Quantum computers may pay a price for keeping time

A quantum computer that runs itself using an internal clock can only compute accurately if that clock is precise, and that precision comes with a thermodynamic cost The post Quantum computers may pay…

• Quantum computers rely on precise timing signals from external sources.
• Autonomous quantum processing unit (aQPU) proposed to operate independently.
• aQPU introduces trade-off between accuracy and thermodynamic costs.
