#Qubits

The most advanced lithography system, crucial for future advanced memory and computer chips, will play a key role in scaling up quantum technology.

Two recent papers suggest that quantum computers may crack modern cryptography sooner than expected

A new "geometry‑based" quantum swap gate makes neutral‑atom computers far less sensitive to laser noise — bringing large‑scale, stable quantum processors a step closer to reality.

Scientists have achieved a breakthrough by "distilling" light to eliminate the noise that prevents photonic quantum computers from scaling.

Algorithmic advances are steadily lowering the bar for quantum attacks—even before large-scale hardware exists.

Google's latest research cuts qubit needs 20-fold to break Bitcoin's elliptic curve encryption, eyeing a 2029 deadline. Crypto scrambles; banks follow. Q-Day looms closer as hardware and algorithms align.

Traditional encryption methods have long been vulnerable to quantum computers, but two new analyses suggest a capable enough machine may be built much sooner than previously thought
