Quantum computing has long been touted as the next revolution to sweep through computation and solve issues now far beyond the reach of any classical computer. An enlightening video on Bloomberg explores huge opportunities available in quantum computing, more so the challenges ahead in trying to harness its power.
This video introduction presents the basic principles that make quantum computers different from their classical versions. Whereas in classical computers, information is represented as bits, in quantum computers, quantum bits, or qubits, are used. Qubits exploit two quantum phenomena called superposition and entanglement to carry out really complex calculations in a parallel way instead of one after another.
The principle of superposition allows qubits to represent multiple states simultaneously, and entanglement, another key factor of quantum mechanics, involves qubits that, when entangled, remain connected in a way that the state of one instantaneously impacts the state of the other, no matter the distance between them. These combined principles allow quantum computers to solve certain problems much faster than any classical computer possibly could today.
The video features industry experts discussing more than a broad spectrum of applications where quantum computing is potentially going to make transformative impacts, ranging from cryptography, material science, and pharmaceutical research to as fine as climate modeling. Quantum computing may finally allow us to simulate material and drug discovery and might accelerate the current pace of innovation by orders of magnitude.
However, the road to workable, widely used quantum computing is strewn with challenges. One of the biggest handicaps facing quantum computing is the problem of quantum decoherence, wherein, through interaction with their environment, the very delicate quantum state of qubits becomes disturbed, hence creating computational faults. That is why researchers are working intensively on methods of coherence time extension and construction of error-correcting algorithms in order for quantum computers to be more robust and reliable.
Added to this are further complications in the attempt at building a functional quantum computer, such as maintaining very low temperatures that keep the qubits stable, an engineering feat that is both complex and costly. The advances are needed at the algorithm level, including those designed to take advantage of quantum architectures with efficacy.
Despite all this, the pace of progress remains incredible, with massive corporations like IBM, Google, and Microsoft investing higher-than-ever resources in researching and developing quantum. Events such as the instigation of IBM's quantum cloud service, as well as the quantum supremacy claim by Google, were pivotal points that really underlined the speed of progress being achieved within this field.
To sum up, that is basically what the video highlights-we are still in the early days of quantum computing, but one day, its benefits may be too great to ignore. As research marches forward, quantum computing continues to be among the most exciting and promising frontiers in technology, heralding an era of new computational power which might indeed change our world.
