Unlike traditional computers that rely on bits of information that can be in one of two states (1 or 0), quantum computers manipulate qubits, or units of information tucked inside subatomic particles. That means, they follow the wacky laws of quantum mechanics and so can be in two states at once. This ability allows quantum computers to theoretically store exponentially more information than your everyday laptop. Live Science is here to dissect the latest achievements and discoveries in this bizarre quantum world of computing.
Latest about quantum computers
Scientists unveil world's first quantum computer built with regular silicon chips

Quantum internet inches closer thanks to new chip — it helps beam quantum signals over real-world fiber optic cables
Researchers used the Q‑Chip to send quantum data over standard fiber using Internet Protocol (IP), showing that future quantum networks could run on today’s internet infrastructure.
Scientists hit quantum computer error rate of 0.000015% — a world record achievement that could lead to smaller and faster machines
The record-breaking achievement could lead to practical, utility-scale quantum computers that are both smaller and faster.
Scientists achieve 'magic state' quantum computing breakthrough 20 years in the making
Scientists demonstrate a process called "magic state distillation" in logical qubits for the first time, meaning we can now build quantum computers that are both error-free and more powerful than supercomputers.
Small, room-temperature quantum computers that use light on the horizon after breakthrough, scientists say
Scientists say they’ve cracked a key challenge in scalable quantum hardware after generating an error-correcting, light-based qubit on a chip for the first time.
'Quantum AI' algorithms already outpace the fastest supercomputers, study says
Researchers have successfully demonstrated quantum speedup in kernel-based machine learning.
