Chip Fabrication: Arsenic Atoms Transform Quantum Tech

UCL researchers have developed a groundbreaking technique using arsenic atoms in silicon that achieves a 97% success rate for single-atom placement (compared to phosphorus’s 70%), potentially solving quantum computing’s twin challenges of error rates and scalability through scanning tunneling microscopy hydrogen resist lithography.

Emergence of opposing arrows of time in open quantum systems

Time May Flow Both Ways: Quantum Physics Reveals New Truth

A groundbreaking study from the University of Surrey reveals that time at the quantum level may flow in both directions, as researchers discovered a mathematical “memory kernel” in open quantum systems that maintains time symmetry even when considering energy dissipation into the universe, challenging our conventional understanding of time’s unidirectional nature.

Breakthrough in Distributed Quantum Computing

Physicists achieved a quantum computing breakthrough by successfully connecting separate quantum processors through photonic links, enabling quantum teleportation of logical gates between modules and demonstrating the first distributed quantum computer system, which could potentially scale up without the limitations of cramming millions of qubits into a single device.
