quantum algorithms:

The process of quantization is supposed to assign to a classical field theory (prequantum field theory) a corresponding quantum field theory. One tends to imagine that in some cases the resulting QFT can itself be regarded as a classical field theory, roughly, and the process of quantization be applied again. One then speaks of *second quantization* .

In its simplest form the *free* second quantization (in the sense of free field theory, introducing no interaction between the second quantized quanta) is identified with the *Fock space* construction on a given space of quantum states.

For interacting second quantization see *sigma-model – exposition of second quantization of sigma-models*.

worldvolume field theory | of fundamental branes | and their second quantization | which in perturbation theory is given by |
---|---|---|---|

worldline formalism | particle | quantum field theory | scattering amplitudes |

2d CFT correlators | string | string field theory | string scattering amplitudes |

In linear type theory, which may be regarded as quantum logic (by the discussion there), the Fock space construction may naturally be identified with the exponential modality. See there for more.
