Quantum computers can solve really hard problems. Unfortunately, they’re brittle. It’s hard to build them, hard to maintain them, hard to get them to do anything, and even harder to interpret the results they give. This is because of something called “decoherence,” which works a lot like entropy.

Computer bits in the quantum world, qubits, share a funky feature of quantum mechanics that makes them act differently when observed than when they’re left alone. That sort of makes any direct measurements of qubit states (reading the computer’s output) difficult.

Time Crystals

Eureka! A research team featuring dozens of scientists working in partnership with Google‘s quantum computing labs may have created the world’s first time crystal inside a quantum computer.

These scientists may have produced an entirely new phase of matter. I’m going to do...

However, for the sake of clarity, there’s two points I need to make first:

  1. Time crystals are a wickedly difficult concept to understand and even harder to explain.
  2. The Google team might have created time crystals. This is pre-print research and has yet to receive full ...

When you put a cube of ice in glass of water, you’re introducing two separate entities (the ice cube and the liquid water) to each other at two different temperatures.

Everyone knows that the water will get colder (that’s why we put the ice in there) and, over time, the ice will get warmer ...

Crystalline structures form in the physical world because, for whatever fundamental scientific reason, the atoms within them “want” to exist in certain exact points.

A time crystal is a new phase of matter that, simplified, would be like having a snowflake that constantly cycled back and fo...

Time crystals have always been theoretical. And by “always,” I mean: since 2012 when they were first hypothesized.

If Google‘s actually created time-crystals, it could accelerate the timeline for quantum computing breakthroughs from “maybe never” to “maybe within a few decades.”

At th...

According to classical physics, the universe is always moving towards entropy . In other words: if we isolate an ice cube and a room-temperature glass of water from all other external for...

But time crystals want to be coherent. So putting them inside a quantum computer, and using them to conduct computer processes could potentially serve an incredibly important function: ensuring quantum coherence.

What Google‘s done, potentially, is prove that humans can manufacture...

Time crystals can survive energy processes without falling victim to entropy. Most importantly, they can do this inside of an isolated system. That means they can consume the cake and then magically make it reappear over and over again forever, without using any fuel or energy. Nearly every far-f...
