The potential for quantum computing to crack other countries’ encrypted networks has captured the attention of national governments. Which of the world’s fundamental challenges could be solved by quantum computing?
What the Heck is Quantum Computing?
Jeffrey Welser of IBM Research explains quantum computing and the big refrigerator next to him. Dean Takahashi of VentureBeat interviewed Welser about it at the Semicon West show in San Francisco, where IBM showed off its IBM Q System’s cooling unit for its quantum processor.
The Race to Develop Quantum Technology is Getting Crowded
Quantum mechanics looks at how particles smaller than atoms interact. At this minuscule scale, entirely different laws of physics apply. But in the global race to develop quantum technology, the U.S. is competing in an increasingly crowded field. NewsHour Weekend’s Christopher Booker reports.
Quantum Computing Leaves the Lab
Dr. Robert Sutor, vice president of IBM quantum computing, strategy, and ecosystem at IBM Research, speaks with Tonya Hall at ZDNet about how quantum computing is changing and becoming more accessible.
What is Quantum Computing?
A brief discussion about quantum computing and artificial intelligence.
Quantum Computers Take Another Huge Leap Forward
Quantum computers continue to advance year over year. Here’s an attempt to round up the biggest quantum computer news in the last year.
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.
