v0.2.8

WaveguideQED v0.2.8

Diff since v0.2.7

Added expect_waveguide() to get expectation value of waveguide operators.
Small bugfix for multiplying LazyTensors with waveguide operators in them

Closed issues:

• Question about Delayed Operators (#49)
• waveguide_evolution for time-dependent Hamiltonian (#53)

v0.2.7

WaveguideQED v0.2.7

Diff since v0.2.6

Bugfix for WaveguideInteraction operators using delayed operators and looping.

Merged pull requests:

• WaveguideInteraction loop bugfix and test update (#51) (@mabuni1998)

v0.2.6

WaveguideQED v0.2.6

Diff since v0.2.5

• Waveguides now loop, so that if the simulation time extends the length of the waveguide state, the time index starts over. This also works with delayed operators, allowing for the simulation of separated emitter, etc. See also #49
• Documentation added that showcases the usage of the above loop mechanic. See: https://qojulia.github.io/WaveguideQED.jl/dev/time_delay/#emitters

v0.2.5

WaveguideQED v0.2.5

Diff since v0.2.4

Waveguide states are no longer, by default, initialized as normalized states. This is to ensure compatibility with creating superpositions / beamsplitter operations. In relation to this, the twophoton initializer was adjusted to so that two photons in the same waveguide now require a prefactor of 1/sqrt(2) in order to be normalized. Documentation was also updated.
Precompilation updated to be faster.
See also: #46 for details on normalization.

Diff since v0.2.3

• To calculate expectation value of waveguide operators ´expect_waveguide´
• Updated how twophoton operators are initialized to allow for non-symmetric wavefunctions
• Added documentation showing how to simulate a twophoton state.
