What is behind the efficiency of Quantum Computers? Quantum Physics.

So, what is it?

To explain at a very basic level, a quantum computer is a computational device that relies on the phenomena of quantum physics. By using the unusual occurrences in the quantum realm to its advantage, the computer is allowed to perform computations in a much faster and effective way.

Quantum physics describes how all the molecules, atoms, and subatomic particles act. …

An in-depth explanation and tutorial of Superdense Coding, a very important quantum communication protocol.


What is it?

Superdense coding is a quantum communication protocol that allows a sender to send two classical bits of information to another user by only utilizing one qubit.

Superdense coding was first proposed by Charles Bennett and Stephen Wiesner in 1992 and experimentally actualized four years later, in 1996.

Now, it is important to note that while Superdense Coding and Quantum Teleportation are closely related, there is a key difference between them. Quantum teleportation is a process by which a user can transmit one qubit using two classical bits whereas Superdense Coding is a process by which a user can transmit two…

What is Quantum Computing?

Quantum Computing is a form of computing that takes advantage of quantum mechanics to process information exponentially faster than classical computers.

Classical computers use classical bits which can consist of either a 0 or a 1 to encode information. Quantum computers, on the other hand, use quantum bits, or qubits, like photons, atoms, ions, etc. to encode information into 2 distinguishable quantum states.

Now you may be thinking, what’s the benefit of using qubits over classical bits? The answer lies in the ability of qubits to behave quantumly, specifically the quantum phenomena of superposition and entanglement.

When a quantum system…

What is Pi?

The constant Pi is one of the most used and widely recognized mathematical constants. Most of us are first introduced to it in elementary school and end up using it all throughout our lives. Pi is the ratio of a circle’s circumference to its diameter.

For thousands of years, pi has been the interest of mathematicians by the likes of Archimedes, Fibonacci, Newton, and Gauss. They’ve all tried to calculate as many digits of pi as they can and applied to different mathematical areas.

“Probably no symbol in mathematics has evoked as much mystery, romanticism, misconception and human interest as…

The Bernstein–Vazirani Algorithm is just another one of the many quantum algorithms in which quantum computers outperform classical computers.


What’s the problem?

So, let’s just say that we are given a box. Hidden in the box is a secret number. This “secret number” is represented by six bits made up of 0’s and 1’s. We need to figure out what the “secret number” is.

In more mathematical terms…

I’ve been a huge procrastinator for my entire life, and honestly, I hate it. Every single assignment, from those I have entire semesters to complete or the 90 minutes during standardized testing, I find a way to procrastinate and put it off. And each time I do this, I dig myself deeper into the habit of wasting time that I’m never going to get back.

I’ve realized that this is in no way shape or form, a healthy or even acceptable habit. I’m trying to become more aware and productive with how I spend my time, to improve my future…
