Edgar Perez shares an article on quantum computing, what it is and how it works, the challenges faced and future impact on society.
What is quantum computing?
Quantum computing is a powerful technology that uses quantum mechanical phenomena, such as superposition and entanglement, to perform computations that are beyond the reach of today’s classical computers.
Quantum computers use qubits, which can exist in a combination of two states at the same time, unlike classical bits that can only be either 0 or 1. Quantum computers can exploit this property to perform parallel operations on multiple qubits, which can speed up certain calculations exponentially.
Quantum computing has certainly the potential to transform the world by enabling new discoveries in fields such as physics, chemistry, cryptography, artificial intelligence and more.
Quantum computing still faces many challenges, such as maintaining the coherence and fidelity of qubits, designing efficient quantum algorithms and scaling up the number of qubits. Quantum computing is still a field in its early stages of development and research, but I expect it to have a significant impact on society in the future.
How does a quantum computer work?
Quantum Computing: No Clear Winner Yet in the Race for Breakthroughs. A quantum computer works by using quantum bits, or qubits, which are physical systems that can exist in a superposition of two states, such as 0 and 1. Unlike classical bits, which can only store one value at a time, qubits can encode both values simultaneously, which allows them to perform parallel operations on multiple inputs.
A quantum computer manipulates qubits using quantum gates, which are devices that apply specific transformations to qubits. By applying a sequence of quantum gates, a quantum computer can implement a quantum algorithm, which is a set of instructions that exploits quantum phenomena to solve a problem.
However, qubits are also very sensitive to noise and interference from their environment, which can cause them to lose their quantum properties and produce errors. This is known as quantum decoherence, and it is one of the main challenges of quantum computing. To prevent or correct decoherence, quantum computers use various techniques such as error correction codes, fault-tolerant architectures and low-temperature cooling systems.
