How to pronounce “qubit” in English

This qubit is very, very fragile and very unstable.

A qubit is not just up or down.

One qubit represents all the possibilities of an object spinning between up and down.

Its qubits are used up.

Audrey's qubit can be entangled with Baxter's qubit in, again, some fixed-temperature environment.

So Audrey's qubit resembles the gas particle bit whose location-- left or right, 0 or 1--

So my qubit and Axel's qubit, or your qubit, are not the same.

so just like one qubit entering here is partially stored here and partially stored there.

So the qubit is a quantum generalization of a classical bit.

That's called a qubit.

So what is a qubit?

So remember a qubit, an example would be an electron, which has this property that when you make an observation of the spin,

Four for the two qubit system.

For a three qubit system, you think about it, ups and downs, you'll find out there are eight possible combinations, and all mixtures of them.

So remember qubit, an example would be an electron, which has this property that when you make an observation of the spin,

For a three qubit system, you think about it ups and downs, you'll find out there are eight possible combinations, and all mixtures of them.

To reset the qubits, you need to cool them even more.

We use it for qubits and quantum superposition.

If you hit 50 qubits-- quantum bits-- then you could surpass any known digital turing machine.

with enough qubits in them.

Thousands of qubits can now be modeled with the latest generation of quantum computers.

For four qubits, then it's two to the power four, there's 16 possible combinations.

For four qubits, then it's two to the power four, there's 16 possible combinations.

So then each being half-- so one qubit you already think is the minimal thing you can have, but one qubit is now stored in two Angel Particles--

So you now approach-- one qubit is just one qubit.

We've had a seven-qubit system in operation.

We are shooting for a 49-qubit system.

So you'll notice with the qubit, I've put these brackets around the 0 and 1.

So repeatedly looking at each qubit and telling me if it's 0 or 1.

So you might call these things a qubit.

So you might call these things a "qubit." So what is a qubit?

The turning point is 50 qubits.

You don't need error correcting qubits.

It really speaks to the number of qubits that you need in order to carry out computations that would be either too time-consuming or maybe

It just means some number of qubits, some number of these physical systems put together to make my quantum computer.

So you prepare some state of your qubits, meaning I manipulate the qubits in a particular way with laser or microwave pulses or things like that.

It's just a formulation of how qubits evolved.

Already we're talking about hundreds of qubits that can be modeled by a quantum computer.

'cause it computes simultaneously on many qubits, not just one after the next, after the next.

so the system of these two qubits.

So the system of these two qubits, let's say they're up and down these spins, right?

at least of a network of 500 qubits.

bi, a qubit, a basic unit of quantum information.

You could also model it with these little qubit parts that you would see.

And it's very easily collapsed into a classical qubit.

For one useful, logical qubits, you have to use 10 to even perhaps 100 error correcting bits to correct one useful qubit.

I'd like to be able to look at a qubit and ask is this qubit a 0 or a 1.

The trick is to sort of burn the correlations between the qubits.

And then an arm span is really four qubits-- one, two, three, four.
