Everything Has a Beginning and End, Right? Physicist Says No, With Profound Consequences for Measuring Quantum Interactions

Quantum technologies require measurements of quantum interactions, but is measuring accuracy possible if we can’t pinpoint the beginning and end in chains of cause and effect over time? Physicist Julian Barbour redefines time as an increasing complexity of interactions, when one arrow of time from the past splits at a “Janus point” into two arrows for the future. Could identifying the Janus point help to resolve the problem of circuit decoherence that has held back full-scale quantum computing?

Quantum Biology Yields Evidence of Superradiance and its Potential for Quantum Information Processing

Quantum biology is an emerging area of research that’s uncovering important features of the cellular signalling networks in living organisms. In networks of tryptophan, a protein-building amino acid, scientists have discovered a process called superradiance that amplifies and efficiently transmits information to and from cells. With implications for quantum information processing, treating Alzheimer’s and dementia, and uncovering more about the microtubules in our brains, quantum biology promises to yield some important clues about cognition in natural neural networks.

Will We Find a Universal Memory for All Physical Scales, From the Tiny Quantum to Giant Stars, in the Geometry of Curves?

In the continuing search for a theory unifying general relativity’s gravity with quantum mechanics, evidence suggests the universe retains a record of events in the geometry of curves that preserve the gravitational consequences of interactions from the tiny quantum to massive stars. We survey 30 years of discoveries pointing to the possibility of decoding probabilities at any scale.

Discoveries in Quantum Teleportation Could Lead to Fault-Tolerant Computers and, Possibly, Wormholes

Quantum teleportation is process that transfers quantum information between locations without moving the quantum bits. A novel method could achieve teleportation without the environmental noise that causes loss of connections in today’s quantum computers, by leveraging the properties of the noise itself. This could lead to fully functional quantum computers, and as a leading scientist explains, possibly the discovery of traversable wormholes.
