How long do you think it will take for quantum computers to reach 1000 qubits entangled?

Just as there is Moore’s Law for the number of transistor’s that can be squeezed on to computer chips, there is also a Moore’s Law for Quantum computing for the increase in the number of Qubits.

Moore’s Law for transistors says that the number will double every two years, while Moore’s Law for Qubits has the number doubling every five years.

The math is very simple: 2 = e^mt   where we know t = 5 years

Taking logs then: ln 2 = 5m, and m = ln 2 / 5 = .1386

Using 50 Qubits as our base, and solving for how many years to reach 1000 Qubits:

1000 = 50 e^0.1386t  , 20 = e^0.1386t solves to: ln 20 / 0.1386 = t years or 21.6 years until we have a quantum computer that has 1000 Qubits.

This result may not seem impressive unless one understands just how powerful a Quantum computer is in terms of the number of Qubits it runs on.

First, let’s look at how the number of classical bits compares with the number of Qubits.

Number of classical bits = 2^{Number of Qubits}

For example, A Quantum computer that runs on only 50 Qubits, is equivalent to a classical computer that runs on 2⁵⁰ bits, that is 1E15 bits! That 50 Qubit Quantum computer runs as fast as our fastest classical computer which operates in the petrabyte range!

Here is a comparison between some numbers of Qubits and their classical equivalents:

 

1000 Qubits is not shown but is easily computed to be equivalent to 1E301 classical bits!

One number that I find personally interesting is how many Qubits would it take to be equivalent to the 86 billion neurons in the human brain.

Again, the math is very simple: 86E9 = 2^{Number of Qubits} , ln 86E9 = Number of Qubits X ln 2

Number of Qubits = ln 86E9 / ln 2 = 36 Qubits

That means a Quantum computer working today with just 51 Qubits can already perform calculations much faster than the human brain.

That does not mean that Quantum computer is more intelligent than humans, only that it can perform calculations much faster than the average human brain.

In fact, this is already true for the average laptop PC today; it too can perform calculations much faster than most humans can and that is what makes them useful to us.

The big scare about A.I. seems to be what will happen when the Quantum computers become so fast that they can calculate in one microsecond what it would take us millions of years to calculate?

Maybe we will know the answer to that in just 22 years when Quantum computers operate on over 1000 Qubits and are millions of times faster than anything that exists today.

Will that sort of computational power lead to self awareness? Only time will tell!
