The Complete WIRED Guide
Quantum computers use the principles of quantum mechanics to perform calculations and operations on data. This new paradigm of computing has the potential to solve certain math puzzles faster than classical computers.
History of Quantum Computing
The prehistory of quantum computing begins early in the 20th century, when physicists began to sense they had lost their grip on reality. Some key milestones include:
-
1980: Physicist Paul Benioff suggests quantum mechanics could be used for computation.
-
1981: Nobel-winning physicist Richard Feynman coins the term quantum computer.
-
1985: Physicist David Deutsch maps out how a quantum computer would operate, a blueprint that underpins the nascent industry of today.
-
1994: Mathematician Peter Shor writes an algorithm that could tap a quantum computer’s power to break widely used forms of encryption.
-
2004: Barbara Terhal and David DiVincenzo develop theoretical proofs showing that quantum computers can solve certain math puzzles faster than classical computers.
The Future of Quantum Computing
Quantum computers have the potential to revolutionize various fields, including chemistry, materials science, and cryptography. They can simulate complex molecular interactions, design new catalysts, and break encryption codes. However, they are prone to noise and interference, which must be addressed before their full potential can be realized.
How Quantum Computers Work
Quantum computers do calculations using bits, too. Qubits can be built in various ways, but they all represent digital 0s and 1s using the quantum properties of something that can be controlled electronically. The magic power of quantum computing is that this arrangement lets qubits do more than just flip between 0 and 1.
Quantum Advantage
Quantum entanglement is a phenomenon where two qubits in a superposition are connected, allowing certain operations on one to instantly affect the other. This property helps quantum algorithms outperform classical ones. Quantum advantage refers to a quantum computer capable of performing a task faster than a state-of-the-art supercomputer.
The Basics of Quantum Computers
A quantum computer does calculations using bits, just like regular computers. However, it uses qubits (quantum bits) instead of classical bits. Qubits can be built in various ways but represent digital 0s and 1s using the quantum properties of something that can be controlled electronically.
The Power of Quantum Computing
The magic power of quantum computing is that this arrangement lets qubits do more than just flip between 0 and 1. Treat them right, and they can flip into a mysterious extra mode called a superposition. A qubit in superposition has some probability of being 1 or 0 but represents neither state.
Future Applications
The future applications of quantum computing are vast and unpredictable, with potential benefits including improved artificial intelligence, more efficient industrial processes, and even carbon capture. Despite the challenges, many experts believe that quantum computers will have far-reaching consequences for society, from finance to everyday life.
