Quantum Supremacy

Verify whether a set of numbers is randomly distributed or not

10,000 years

3 minutes & 20 seconds

It is on the hardware level -> whether the current is flowing
through a transistor or not

If current is allowed it's "on" state or 1

If current is blocked it's "off" state or 0

In "on" state - no barriers

In "off" state - a barrier cuts off the flow of electrons

The smallest working transistor ever created is 1nm

Red Blood Cells - 10,000 nm

Bacteriophage virus - 15 nm

Modern Transistors - 7 nm

∝

Smaller the size of the barrier blocking the electron

Which only happens in the "Quantum realm"

4 Bits -> can have only 1 of all possible 2^4 values

Problem solving is basically going through all the 2^4 values and finding that one required value

Might sound stupid

Photon may be polarized both vertically & Horizontally when it is
not observed

While bit is 0 or 1

Regular Computers - O(n)

Quantum Computers - O(√n)

Time complexity of 3162

Prime Factorization of large number (1024 bit)

Quantum Computers can simulate theoretical chemistry much more efficiently

Simulate how a drug interacts with the human body greatly increasing the efficiency of drug production

Predict how a pandemic will spread by crunching the numbers & provide effective response strategy

0ms response time

No matter how far they are!
