How Quantum Computers Could Change the World

The reality of subatomic level is different than the reality we are familiar.

One of the possibilities includes the ability of such particles to communicate with each other instantly, from afar (called entanglement).

Quantum computers can find solutions much faster than classical computers. Such may solve problems that cannot be evaluated by classical systems since quantum computers can analyze exponentially more complex data and at much faster rates.

We are still in the infancy of analyzing subatomic particles and the promise of this technology will not be realized for a number of years.

How Quantum Computing Works

Quantum computing can solve problems that would take classic computer a lifetime to process. Quantum computers use quantum bits, or qubits, that researchers believe will be able to process information exponentially faster than any computer we have today. Researchers also believe that quantum computing will help humanity solve some of the toughest problems facing our existence. This video also discusses topological qubits, which are considered to be more stable.

How it Works: Quantum Computing

Quantum computing has the potential to solve some of the world’s most complex problems. So how are quantum computers different from the traditional computers we use today?

Quantum physics describes how the world works at its most fundamental level.

Quantum computing has become one of the leading applications of quantum physics.

Quantum computers are not going to replace classical computers. But their radically different way of operating allows them to calculate in ways that classical computers cannot.

Classical computers encode information in bits. And each bit can represent a 0 or 1 (on or off).

Instead of bits, quantum computers have qubits, which make use of two key principles of quantum physics: Superposition and entanglement.

Superposition means that each qubit can represent a 0 or 1, or both at the same time.

Entanglement occurs when two qubits in a superposition are correlated with one another, meaning the state of one (whether 0, 1 or both) depends upon the state of another qubit.

Using these two principles, qubits can solve problems that are virtually impossible with classical computers.

In brief, quantum computers can examine exponentially more states than classical computers.

Quantum Computing is the Future… Eventually

In this video, Jason Ball introduces some basic concepts of quantum mechanics and quantum computing, including its advantages and disadvantages.

This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

Jason Ball is a PhD student in quantum information science, a former teacher, and the father of a budding young scientist, Jason has a passion for teaching physics.

IBM Unveils Groundbreaking Quantum Computing System

Bob Sutor is the VP of IBM’s Q Strategy and Ecosystem, or “IBM Q.”

Quantum computing uses a radically new type of computing, really from the ground up, which is hoped to solve some problems that are not possible for classical computers, such as a laptop.

IBM Research Headquarters, in Yorktown, NY, has more quantum computers than the rest of the world combined.

The Q System One is the first quantum system to consolidate thousands of components into a glass-enclosed, air-tight environment built specifically for business use.

We’re Close to a Universal Quantum Computer, Here’s Where We’re At

Quantum computers have the potential to completely change how we use technology in the future.

Quantum computers are new kinds of machines that promise and exponenetial growth spurt in processing power, capable of tackling problems our computers of today can’t solve.

Quantum mechanics is the field that describes the simplest things around us, individual electrons or atoms, or particles of light, like photons.

These simple systems don’t obey the same rules that the world around us does.

Two important properties of quantum mechanics are superposition of states and the other one is entanglement.

With superposition, instead of using bits, that represent zeros or ones in classical computing, qubits are used, which are quantum bits, and they can be any combination of a zero or one, instead of only a zero or a one.

A special form of superposition is known as entanglement, which is the ability to have two qubits in superposition states, which can only be understood with a collective element of both qubits.

Different qubits can have this persistent ghostly connection with each other and if you flip one qubit around another one will feel it. And if you do this in a controlled way, you can move lots of information around with your quantum mechanical system really efficiently.

Coherence time is how long quantum information lasts inside of a qubit.

Quantum computers are still in the experimental stage, but their raw potential and imminent arrival are sure to cause a paradigm shift in computing, physics and potentially our understanding of the world we live in today.
