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.

A new route to perfect energy absorption

A fundamental physics discovery could help reduce energy losses in future wireless power technologies The post A new route to perfect energy absorption appeared first on Physics World .

  • Introduces Transient Coherent Perfect Absorption (TCPA) during system activation.
  • Waves interfere out-of-phase, canceling reflections and maximizing absorption.
  • Potential to improve wireless power transfer and energy delivery efficiency.
