 Quantum computing has the potential to solve problems that no one ever could using classical computers. Its promise runs from cryptography revolutions to drug discovery accelerations, with much in between. Despite several decades of research and investment, however, quantum computing is not yet an applied science. 1. Hardware Challenges Quantum computers are highly fragile and operate near absolute-zero temperatures to preserve the quantum states. Main challenges are: Quantum Decoherence: Qubits lose their state due to noise in the environment, and thus, computation becomes unreliable. Error Rates: Quantum operations are erroneous with a high error rate, and so error correction becomes essential, which increases resource requirements substantially. Scalability: Producing systems that would have millions of reliable qubits necessary for practical applications is a Herculean task. 2. Software and Algorithm Development The software ecosystem for quantum computing is in its infancy. A...

  1. Breaking Classical Cryptographic Algorithms Exponential speedup of the calculation in a quantum computer makes a number of broad-used cryptographic systems insecure: RSA, ECC, and DSA Encryption: Shor's algorithm factors large integers efficiently which means that RSA and similar encryption methods can be easily broken. Discrete Logarithm Problem (DLP): Quantum computers solve DLP problems efficiently which contradicts the security of elliptic curve cryptography (ECC). 2. Quantum Key Distribution (QKD) Principles of quantum mechanics make possible secure key distribution, revolutionizing cryptographic practices: Unbreakable Security: QKD protocols such as BB84 and E91 utilize quantum properties such as superposition and entanglement to guarantee that any eavesdropping attempt disturbs the quantum state, thus alerting the parties. Applications in Secure Communication: QKD is already being applied in sensitive areas like military communications and financial transactions. 3. Ran...

Quantum Computing vs. Classical Computing 1. Basic Principle Classical Computing: Classical bits that can be in one of two states: 0 or 1. Quantum Computing: Quantum bits (qubits) that take advantage of quantum phenomena such as superposition (being 0, 1, or both at the same time) and entanglement. 2. Processing Power Classical Computing: Sequentially or in parallel processes work by binary logic. Its ability to compute depends on the bits used and how fast the transistor moves. Quantum Computing: Certain tasks it could solve a problem exponentially faster. It achieves this by handling all possibilities at once, given its principle of superposition and quantum interference. 3. Applications Classical Computing: Suitable for most general-purposes computations including web surfing, word and text documents generation, playing, and simple simulation. Quantum Computing: Ideal for solving complex problems in areas such as cryptography (encryption breaking), optimization, drug discovery, and ...
