Quantum Computing: Beyond Binary Brilliance

“What is quantum computing”

Quantum computing is a branch of computing that relies on principles and theories of quantum mechanics. Unlike classical computers, which uses bits (either 0s or 1s) to represent information, quantum computers uses quantum bit or qubits. It is calculated that a quantum computer is approximately 155 million times faster than the most powerful supercomputer we currently have in the today’s world. It would approximately take 1000s of years to a supercomputer to calculate what a quantum computer can calculate in seconds.

What is Qubit

A qubit or a quantum bit, is the fundamental or basic unit of information in quantum computing. Unlike classical bits, which can exist in one of two states (0 or 1), qubits can exist in multiple states simultaneously, using a quantum property called superposition. This ability to exist in multiple states at the same time is a key feature that gives quantum computers their potential for parallelism and increased computational power. Qubits are manipulated using quantum gates, which perform operations on the qubit’s state. Quantum computers use a combination of superposition, entanglement, and quantum gates to perform complex calculations more efficiently for certain types of problems compared to classical computers.

In classical computing, bits are like switches that can be either on (1) or off (0). In contrast, qubits can represent both 0 and 1 simultaneously, and their state is described by a combination of these two possibilities. Mathematically, the state of a qubit in superposition can be represented as an equation combining the 0 and 1 states.

Cloud Quantum Computing

Quantum computers achieve their enormous computing power through taking laws of quantum physics in account, and when a user is allowed to access these quantum computers through servers or internet then it is called cloud quantum computing. In other words, it is a quantum computer that users can access and utilize remotely, without the need to own or maintain the physical hardware.
