PyCCE 1.1.1

Corrected corr.py error

PyCCE 1.1

The major update contains methods to compute spin dynamics with the addition of single-spin jump operators in the form of a Lindblad master equation.

PyCCE 1.0.1.3a

Fixed a hamiltonian broadcasting bug.

PyCCE 1.0.1.3

Fixed a bug when gcce calculation with delay provided in pulse sequence but no bath spin pulses produced incorrect results.

PyCCE 1.0.1.2

Fixed bug with interlaced averaging

PyCCE 1.0.1.1

Bug fixes:

Fixed bug with broadcasting
Fixed bug with attributes of heterogeneous bath

PyCCE 1.0.1

Fixed a bug in projected_addition for the case of multiple central spins.

PyCCE 1.0.0a

Major release! Reupload due to the crutial bug. Highlights include:

• Support for several central spins with the new class CenterArray! Check out a new tutorial to see how to use PyCCE to study the entanglement between two dipolarly coupled NV centers in diamond.
• Direct definition of the bath spin states with BathArray.state attribute.Expanded the control over pulse sequences. See Pulse class for details.
• EXPERIMENTAL FEATURE. Added ability to define your own single particle Hamiltonian. See BathArray.h and CenterArray.h for details.
• Significant overhaul of computseveral central spins with the new class CenterArray! Check out a new tutorial to see how to use PyCCE to study the entanglement between two dipolarly coupled NV centers in diamond.
• Direct definition of the bath spin states with BathArray.state attribute.Expanded the control over pulse sequences. See Pulse class for details.
• EXPERIMENTAL FEATURE. Added ability to define your own single particle Hamiltonian. See BathArray.h and CenterArray.h for details.
• Significant overhaul of computational expensive parts of the code with Numba. This makes the first run of PyCCE quite slow, but after compilation it should run observably faster.
• Various bug fixes and ational expensive parts of the code with Numba. This makes the first run of PyCCE quite slow, but after compilation it should run observably faster.
• Various bug fixes and QoL changes.

Pulses bugfixes

Fixes several bugs:

When no rotation is given for both the central spin and the spins in the cluster it now properly ignores it
parallel=True keyword in gcce works properly
Doesn't raise an error if sum of the delays is very close to the timesteps

Bugfixes

Several bugfixes in this release:

fixed external_bath bug
fixed cube
