About two decades ago, quantum computing researchers developed an algorithm that uses the laws of quantum mechanics to solve a type of mathematical maze much faster than any regular computer algorithm. But there is a problem: this speed-up has a downside. The quantum algorithm gets to the exit, but it doesn’t know how it got there.
Speed that burns the past?
Fast & Furious
Imagine walking through a giant maze to find an exit. In classical computing, or normal search, you’d probably explore each path one at a time, marking dead ends and retracing your steps in a slow, methodical process. That’s how conventional search algorithms often work, solving problems by exploring possibilities one at a time. But a quantum computer uses superposition to consider multiple paths through the maze simultaneously, rather than exploring one path at a time. That means a quantum search narrows down the possibilities by using interference patterns to amplify correct paths and cancel out incorrect ones, rather than methodically trying every path. But the fury of this rapid computational advance erases a past that, for the time being, cannot be restored.

Quantum computing
Science fiction concepts aside, the incredible gain in efficiency of quantum computing is made possible by the fundamental principles of quantum mechanics. Quantum mechanics isn’t some abstract, distant thing—it affects us closely. It’s inextricably linked to our existence. We exist together with the particles.

Quantum computers are fast because they use the principles of entanglement—instantaneous communication, theoretically faster than light—and superposition—multiple simultaneous locations—to solve complex problems. Conventional computers use basic units of information called bits; quantum computers use quantum bits, or qubits, which work in a completely different way. In superposition, qubits can represent all possible states of a system at once, like being on all the paths of the maze at once. In addition, entanglement allows qubits to hold information that is influenced by each other, even when separated by large distances, reducing processing time.
