Origin and Evolution of Quantum Computers #
Scientists like Richard Feynman and Yuri Manin ignited the flame of quantum computing back in the early 1980s. Feynman presented the following conundrum in 1981 at MIT: Classical computers cannot effectively replicate the evolution of quantum systems. Thus, he put up a fundamental design for a quantum computer that could do these simulations.
The algorithm created by Peter Shor in 1994 enabled quantum computers to factorize huge integers efficiently and exponentially quicker than the best classical algorithm on conventional machines. To factor 300-digit figures, the latter requires millions of years. Theoretically, the Shor algorithm is very much able to defeat many of the current cryptosystems. Interest in quantum computing and its applications was sparked by the idea of employing quantum computers to break cryptosystems in hours as opposed to millions of years.
A quantum database search algorithm was created in 1996 by Lov Grover that could solve various issues that required a random or a brute-force search four times faster.
Grover’s and other pioneering quantum algorithms were successfully solved in 1998 using a functional 2-qubit quantum computer. More and more applications were created as the race for a new era of computing power started.
The race reached a new level in 2017 when IBM unveiled the first commercially viable quantum computer.
Working Principle #
Now, let us understand how a quantum computer works in simple terms. A traditional computer is really just a calculator that interprets and makes judgments about the data we input in accordance with predetermined instructions by using a sequence of bits—values of 0 and 1 to indicate two states (suppose on and off switch).
The quantum equivalent of computer bits is called qubits, a short term for quantum bits. Unlike bits, qubits can exist in either of the two states or two states simultaneously. This property enables them to store a humongous amount of information at the cost of less energy.
New Breakthrough #
Building a reliable, fault-tolerant quantum computer is one of the most daunting and challenging tasks faced by researchers and scientists today. As quantum computers continue to grow larger in size, researchers keep going back and forth between trying to shrink them down to their functional sizes and trying to suppress all the noisy defects.
The fundamental reason for this is that the probabilistic approach that is opted for creating qubits. relies on random states, is challenging to use to manufacture qubits reliably. To put it in simple words, scientists essentially mash stuff together until the desired outcome shows up.
When it comes to qubits, the bigger the size, the better. But, unwanted noise keeps increasing as qubits grow in size. To do away with this issue, the scientists and researchers at the renowned Max Planck Institute for Quantum Optics took a different route, and what they have come up with might turn out to be the biggest game changer in the field of quantum computing.
According to the paper published by the said team of researchers, they have managed to present the biggest entangled states of optical photons to date using a scalable and flexibly programmable source of entangled photons. They have also added that insofar as probabilistic entangling gates are not necessary, it is deterministic in nature. As a result of this, they have outscored earlier systems in terms of scaling by a large margin.
Google Time Crystals #
A team of scientists collaborated with Google’s quantum computing labs to develop the world’s first-time crystal within a quantum computer. This might be the biggest scientific achievement we are going to witness in our lifetime. Like a crystal’s structure, a time crystal repeats in time and, critically, does so eternally and without further energy input - much like a clock that runs eternally without the need for batteries. The pursuit of this phase of matter has long been a theoretical and experimental challenge, and it has now finally been realized. This might be a huge step forward in the field of quantum computing and might open new horizons that can fundamentally change our understanding of the field.
In conclusion, all these rapid and impressive changes can potentially alter the world of quantum computing and open up newer, faster, and more efficient ways we carry out quantum computing operations.
