Classical vs Quantum Computing

Classical computing

Classical computing uses the classical bits. In classical computing, Algorithms often need many parallel computations, which can be time-consuming.

Classical software development translates source code from a programming language into specific ‘machine code’ for a platform, and performs operations (gates) on thousands of transistors.

Quantum Computing

Quantum computing are high-performing machine based on quantum physics. They use qubits for quantum computing. Quantum computers are faster than any classical computer.

Quantum programming Considers multiple options simultaneously, enabling an algorithm to run across all options in a single step. They solve problems more effectively when compared with classical computers.

Quantum computing is not scalable as qubits are highly sensitive to environmental circumstances, which significantly makes scaling difficult.

Programs in Quantum Computing are Probabilistic

Quantum programs handle probabilities for outcomes, unlike classical programs that deterministically produce 0 or 1.

Quantum Computing Operations Must be Reversible

Quantum circuits must be reversible to recover input states from outputs; most classical circuits are not inherently reversible

Advancing quantum computing

Advanced quantum computing involves discovering different ways to convey quantum applications through high-level abstractions, and then compiling and mapping these onto quantum simulators.
