But one key challenge stands in the way: speed.
To be reliable, quantum computers must perform calculations and error corrections before their fragile quantum bits, or qubits, lose coherence.
Now, MIT researchers have built a new superconducting circuit that could dramatically speed up this process.
Scientists are working to send quantum information through existing fiber networks. This shift could save billions in infrastructure costs and speed up the arrival of quantum-powered technologies.
Unlike regular data, quantum communication sends information through single photons. These photons hold fragile quantum states that are easy to disturb. That makes sharing fiber lines with classical Internet traffic a serious technical challenge.
Classical signals, especially those powered by lasers, flood the fiber with light. This generates a kind of noise called inelastic scattering. One type, known as spontaneous Raman scattering, floods the line with stray photons that can drown out the quantum signals.
Researchers have shown that they can distribute quantum keys under realistic conditions using commercial lasers.
Florida State University Assistant Professor of Physics Zhengguang Lu and fellow researchers have discovered new states of matter in graphene — a form of
What if gravity isn’t a force, but a computation? In this episode, we explore Dr. Melvin Vopson’s groundbreaking theory that gravity emerges from the universe’s effort to compress and optimize information. Discover how this idea connects with simulation theory, quantum physics, and the future of reality.

In a new demonstration, a U.S. researcher showcased that a quantum computer outperforms supercomputers in approximate optimization tasks.
The University of Southern California-led (USC) study demonstrated the first quantum scaling advantage for approximate optimization problem-solving using a quantum annealer.
Quantum annealing is a specific type of quantum computing that can use quantum physics principles to find high-quality solutions to difficult optimization problems. Rather than requiring exact optimal solutions, the study focused on finding solutions within a certain percentage (≥1%) of the optimal value, according to researchers.
Researchers at the University of Hong Kong used special models to simulate the phase transition from one quantum state to another.
A new MIT-designed circuit achieves record-setting nonlinear coupling, allowing quantum operations to occur dramatically faster.
The heart of this advance is the “quarton coupler,” which boosts both light-matter and matter-matter interactions. This progress could lead to quicker quantum readouts, crucial for error correction and computation fidelity.
