IonQ's breakthrough, announced this week, brings us closer than ever before to unlocking the quantum internet. DARPA is taking note, and the company's stock is soaring.

Shares of Sealsq rose after the company said its Quantum Fund portfolio company EeroQ achieved a breakthrough in autonomous quantum computing laboratories. The stock rose 10% to $2.86 in premarket trading.

In-memory computing, which processes data directly within memory units, is emerging as a powerful solution to overcome the energy and speed limitations of modern computers. Scientists in China have developed a quantum-enhanced stochastic system using a room-temperature quantum memory.

A major obstacle in the development of powerful quantum computers is the growing number of cables required to control a computer as the number of qubits increases. Researchers at Chalmers University of Technology in Sweden have now demonstrated that several qubits can share the same cable—without significantly increasing computation time.
