Physicists have successfully demonstrated a quantum 'lie detector' by testing Bell correlations in a 73-qubit system, confirming genuine quantum behavior in large, complex systems, which advances the development of truly quantum computers and quantum technologies.
Researchers have developed a new method using quantum entanglement and blockchain technology to generate and verify truly random numbers, overcoming the limitations of traditional pseudo-random generators and enhancing security for applications like cryptography and public lotteries.
Researchers at NIST and the University of Colorado Boulder have developed a public, verifiable quantum random number generator called CURBy, which uses quantum nonlocality and Bell tests to produce truly random numbers that are certifiable and traceable, marking a significant milestone in the use of quantum physics for secure and unbiased randomness generation.
A new experiment using a 30-meter-long tube cooled to close to absolute zero has confirmed the possibility of quantum entanglement, which Albert Einstein was skeptical about. The experiment ran a Bell test using superconducting circuits, which could play a significant role in the development of quantum computers. The experiment is structured in a way that could be used for practical applications, such as secure encrypted communications. The research shows the promise of qubit technology and could eventually find its way into full-scale quantum computers.
Researchers at ETH Zurich have performed a loophole-free Bell test with superconducting circuits, confirming quantum mechanics and disproving Einstein’s local causality concept. The findings open up possibilities in distributed quantum computing and quantum cryptography. The researchers were able to perform the experiment using superconducting circuits for the first time, which are considered promising candidates for building powerful quantum computers. The experiment confirms that superconducting circuits operate according to the laws of quantum mechanics too, even though they are much bigger than microscopic quantum objects such as photons or ions.
Researchers at ETH Zurich have performed a loophole-free Bell test using superconducting circuits, further disproving Albert Einstein's concept of local causality and providing confirmation for quantum mechanics. The experiment also confirms that superconducting circuits operate according to the laws of quantum mechanics and opens up possibilities for practical applications in cryptography and distributed quantum computing. The researchers built an impressive facility containing a 30-meter-long vacuum tube connecting two cryostats containing superconducting circuits, which were entangled and subjected to random measurements to violate Bell's inequality.
