Quantum Computing

Computation using quantum superposition and entanglement.

Almanac Watching a Photon Without Touching It
  • How did Wineland use trapped ions and laser pulses to build the first quantum logic gates?
  • What modern technologies depend on the quantum measurement techniques Haroche and Wineland developed?
Almanac Even Einstein's Intuition Lost
  • What did John Bell's 1964 theorem propose as a way to test whether hidden variables underlie quantum mechanics?
  • What practical technologies depend on the entanglement these three physicists proved is real?
Almanac A Promise That Finally Felt Like a Deadline
  • Why were earlier quantum advantage claims, like Google's 2019 Sycamore result, disputed by other researchers?
  • What was the Quantum Echoes algorithm, and how much faster was Willow than the Frontier supercomputer on it?
  • How was the 2025 Willow experiment designed to make its result independently verifiable and reproducible?
Almanac A Secret That Notices Being Watched
  • How does the BB84 protocol use quantum mechanics to detect eavesdropping on a transmitted key?
  • What did Bennett and Brassard's work later contribute to quantum teleportation and quantum error correction?
  • Why was the 2025 Turing Award seen as recognizing a foundation for an entire new computing paradigm rather than a single cryptographic trick?
