The quantum harmonic oscillator models systems experiencing a restoring force proportional to displacement, predicting quantized energy levels determined by integer values of "v" representing vibrational states.
GKP codes are a class of quantum error correction schemes encoding qubits into continuous variable states like Gaussian states to protect against loss and noise, utilizing annihilation and creation operators.
A coherent state is a specific quantum state of a harmonic oscillator exhibiting properties remarkably similar to classical expectations, minimizing uncertainty between position and momentum.
Cat state, derived from Schrödinger's thought experiment, describes a quantum system existing in multiple contradictory states simultaneously—like a cat being both alive and deceased—until measured.
Zero-point energy describes the lowest possible energy state of a quantum mechanical system; even at absolute zero temperature, fluctuations persist due to the Heisenberg uncertainty principle.
