IonQ Inc. IONQ shares are up during Wednesday’s premarket session as the company was selected for DARPA’s Heterogeneous Architectures for Quantum (HARQ) program. The initiative announced on Tuesday aims to develop high-speed quantum interconnects that can link various types of quantum computers,

Quantum computing future explained through cryptography, optimization, and AI breakthroughs showing how quantum computing technology reshapes modern computation.

A team of physicists set out to test some of the most exciting claims in quantum computing—and found a very different story. Instead of confirming breakthroughs, their careful replication studies revealed that signals once hailed as major advances could actually be explained in simpler ways.

Co-authored by BTQ Chief Quantum Officer Dr. Gavin K. Brennen, the research introduces a new error-correction framework for permutation-invariant codes--an enabling step toward more reliable quantum systems at scale.

Two research groups say they have significantly reduced the amount of qubits and time required to crack common online security technologies.

Quantum hardware and software are advancing rapidly – and our online encryption systems need to change to stay ahead.

The SEALSQ Quantum Vertical Stack is structured as four foundational security layers and three operational quantum verticals, unified by the SEALQuantum photonic interconnect platform and capped by the Quantum Spatial Orbital Cloud (QSOC):

A new brief from the Bitcoin Policy Institute says advances in quantum computing may bring forward risks to Bitcoin’s cryptography, though developers are already working on fixes.

Quantum computing represents a forced development opportunity, not a fatal flaw. The winners will not be those who avoid the risk, but those who operationalize the transition, embedding quantum resilience into governance, reporting, and technical design before the threat fully materializes.

Quantum computing advances are improving stability and error correction, bringing practical machines closer and raising future impacts for security and science.
