Quantum marbles in a bowl of light

Date Posted: 27th December 2021


Which factors determine how fast a quantum computer can perform its calculations? Physicists have devised an extravagant experiment to answer this question.

But before that, what is a Quantum Computer?

A quantum computer is a machine that uses some of the unique properties of quantum physics to solve problems that are too complex for regular computers, or sometimes, even supercomputers. It focuses on how energy and matter behave at the subatomic level. They rely on quantum properties like superposition, interference, and entanglement, to perform calculations.

The qubit or quantum bit is the basic unit of quantum information in quantum computers. In regular computing, the information is encoded in bits, where each bit has the value 0 or 1. In quantum computing, the information is encoded in qubits. A qubit can be in state 0, 1 or (unlike a bit) in a linear combination of both states (i.e. superposition of 0 and 1).

What are Quarks, Leptons and Bosons?

    Table of contents  WHAT ARE  QUARKS, LEPTONS  AND  BOSONS? View my previous article here - How were Neutrinos Discovered? View the next article here - The Fundamental Forces ----------------------------------------- Here is a brief overview of what are quarks, leptons and bosons - families of particles that make up the Standard Model! (Based on what has been discussed so far).  * ADDITIONAL * -  A fermion is any particle that has an odd half-integer (like 1/2, 3/2, and so forth) spin.  Quarks  and  leptons , as well as most composite particles, like  protons  and  neutrons , are fermions. QUARKS: Quarks are subatomic particles that are found in protons and neutrons in the atomic nucleus. There are 6 quarks .  Up quark and Down quark belong to the first generation. Charm quark and Strange quark belong to the second generation. Top quark and Bottom quark belong to the third generation. The second and third generation particles are more massive and unstable when compared to the

Particle Physics - Introduction

Table of contents   PARTICLE PHYSICS - INTRODUCTION View the next article here - More on Particle Physics and Why it matters? ----------------------------------------- What is Particle physics? Let me give a hint by telling you what particles are? Everything in our universe is made up of extremely small components known as particles. Now did you get it? Particle Physics is nothing but the study of how our universe was made and what our universe is constituted of. To prove their existence and see how they behave, scientists observe them until the particles leave a sign. Often, instead of waiting for the particles to leave a sign, they make particles by colliding known particles. How? Well, the accelerators speed up the known particles almost to the speed of light. The particles collide and release massive energy, which results in the creation of new particles. This is why Particle physics is also known as High Energy Physics . At present, there are 17 particles that have been identifie

    Table of contents  COSMIC RAYS View my previous post here - The Survival of a Neutron View the next article here - (Coming soon!) ----------------------------------------- Cosmic Rays are super fast subatomic particles "raining" down on us from space.  These high-energy particles arriving from outer space are mainly (89%) protons – nuclei of hydrogen, the lightest and most common element in the universe – but they also include nuclei of helium (10%) and heavier nuclei (1%), all the way up to uranium. (Source of information: CERN) Their origin remains to be a mystery.  These are radiations or rather little bits of atoms whizzing by us, even through us, all the time! We cannot feel them, because they don't affect the human body . However, they do show their presence in different ways. For instance, they cause computers to malfunction . Scientists have been studying cosmic rays since the early 1900s. At the beginning of the 20th century, around 1911, a physicist, Vict
