Quantum Memories in Quantum Networking and Computing
Quantum memories are devices capable of storing quantum states (qubits) in a stable form without collapsing their quantum properties. In essence, a quantum memory is the quantum-mechanical analog of classical computer memory or RAM.

Quantum Technology Use Cases in Energy & Utilities
Quantum technologies matter for energy because many challenges in this sector involve combinatorial optimization and molecular simulation at scales classical computers cannot handle. For example, routing power through a grid with thousands of control decisions or modeling the chemistry inside a battery are tasks that overwhelm today’s fastest supercomputers. Quantum computers leverage phenomena like superposition and entanglement to examine a vast number of configurations simultaneously,…

Fidelity in Quantum Computing
Fidelity in quantum computing measures the accuracy of quantum operations, including how effectively a quantum computer can perform calculations without errors. In quantum systems, noise and decoherence can degrade the coherence of quantum states, leading to errors and reduced computational accuracy. Errors are not just common; they're expected. Quantum states are delicate, easily disturbed by external factors like temperature fluctuations, electromagnetic fields, and even stray…

Quantum Errors and Quantum Error Correction (QEC) Methods
Quantum error correction (QEC) is therefore critical for enabling large-scale or fault-tolerant quantum computing. Fault tolerance means a quantum computer can continue to operate correctly even when individual operations or qubits error out. Unlike classical error correction – which can simply duplicate bits and use majority vote – quantum error correction must delicately handle qubit errors indirectly (via entanglement and syndrome measurements) to avoid collapsing…

Neven’s Law: The Doubly Exponential Surge of Quantum Computing
In 2019, Google’s Quantum AI director Hartmut Neven noticed something remarkable: within a matter of months, the computing muscle of Google’s best quantum processors leapt so quickly that classical machines struggled to keep up. This observation gave birth to “Neven’s Law,” a proposed rule of thumb that quantum computing power is advancing at a doubly exponential rate – far outpacing the steady exponential progress of…

The Toffoli Gate: The Unsung Workhorse in Quantum Codebreaking
Understanding the Toffoli gate’s role isn’t just an academic exercise – it has real implications for when and how quantum computers might break our cryptography. Each Toffoli gate isn’t a single physical operation on today’s hardware; it has to be decomposed into the basic operations a quantum machine can do (typically one- and two-qubit gates). In many quantum architectures, a Toffoli might be broken down…
