Holographic Quantum Error Correcting Codes

Exploring the intersection of quantum gravity in the theory of quantum error correction.

Quantum error-correction is necessary if we want to have fault-tolerant quantum computers that possess the massive computational capability to solve some exponentially hard problems. Qubit systems become more and more susceptible to noise as they scale up in number. Error-correcting codes that can fix bit-flip errors are important in outputting accurate results from our quantum computers.

Holographic quantum error-correcting codes are a new method to approach this problem and they were introduced by the famous physicist John Preskill. To understand how they work we need to dive deeper into the theoretical side of quantum gravity and the holographic principle.

Quantum Mechanics + General Relativity = ?

We suck at explaining how the universe works as whole, there are direct distinctions between the laws of small things (atoms) versus big things (planets).

The biggest challenge for theoretical physicists over the past couple decades has been to find a unifying theory between general relativity and quantum mechanics. The most incompatible theories which work separately but never together! We need both…
