The HARDEST Machine Humanity Has Ever Tried to Build

追加: 2026-05-23

[00:00:00]The very thing [music] that makes quantum computers so powerful, their ability to tap into the delicate subatomic fabric of the universe, also makes them a nightmare to build.

[00:00:11]Engineering [music] a general-purpose fault-tolerant quantum computer is arguably the single hardest engineering challenge humanity has [music] ever taken on.

[00:00:22]Qubits are incredibly fragile. They are the ultimate divas of [music] the physics world.

[00:00:28]To maintain that spinning coin state of superposition, a qubit must be completely isolated [music] from the outside universe.

[00:00:37]Any interaction with the environment, a stray photon of light, a microscopic fluctuation in [music] magnetic fields, a passing Wi-Fi signal, or even a tiny [music] variance in temperature causes the qubit to crash out of its quantum state.

[00:00:54]In physics, this is called decoherence.

[00:00:56][music] The quantum magic vanishes, and your multi-million-dollar super machine instantly becomes an [music] oversized paperweight.
