Wed Feb 26 03:56:01 UTC 2025 - Steve Kowalik <steven.kowalik@suse.com>
- Update to 1.10.0:
* Breaking Changes
+ renamed MatrixProductState.partial_trace and MatrixProductState.ptr to
MatrixProductState.partial_trace_to_mpo to avoid confusion with other
partial_trace methods that usually produce a dense matrix.
* Enhancements:
+ tensor network fitting: add method="tree" for when ansatz is a tree -
tensor_network_fit_tree
+ tensor network fitting: fix method="als" for complex networks
+ tensor network fitting: allow method="als" to use a iterative solver
suited to much larger tensors, by default a custom conjugate gradient
implementation.
+ tensor_network_distance and fitting: support hyper indices explicitly
via output_inds kwarg
+ add tn.make_overlap and tn.overlap for computing the overlap between
two tensor networks, ⟨ O | T ⟩ , with explicit handling of outer
indices to address hyper networks. Add output_inds to tn.norm and
tn.make_norm also, as well as the squared kwarg.
+ replace all numba based paralellism (prange and parallel vectorize)
with explicit thread pool based parallelism. Should be more reliable
and no need to set NUMBA_NUM_THREADS anymore. Remove env var
QUIMB_NUMBA_PAR.
+ Circuit: add dtype and convert_eager options. dtype specifies what the
computation should be performed in. convert_eager specifies whether to
apply this (and any to_backend calls) as soon as gates are applied
(the default for MPS circuit simulation) or just prior to contraction
(the default for exact contraction simulation).
+ tn.full_simplify: add check_zero (by default set of "auto") option
which explicitly checks for zero tensor norms when equalizing norms to
avoid log10(norm) resulting in -inf or nan. Since it creates a data
dependency that breaks e.g. jax tracing, it is optional.
+ schematic.Drawing: add shorten kwarg to line drawing and curve drawing
and examples to {ref}schematic.
+ TensorNetwork: add .backend and .dtype_name properties.
+ add Circuit.sample_gate_by_gate and related methods
CircuitMPS.reordered_gates_dfs_clustered and
CircuitMPS.get_qubit_distances for sampling a circuit using the
'gate by gate' method introduced in https://arxiv.org/abs/2112.08499.
+ add Circuit.draw for drawing a very simple circuit schematic.
+ Circuit: by default turn on simplify_equalize_norms and use a
group_size=10 for sampling. This should result in faster and more
stable sampling.
+ Circuit: use numpy.random.default_rng for random number generation.
+ add qtn.circ_a2a_rand for generating random all-to-all circuits.
+ expose qtn.edge_coloring as top level function and allow layers to be
returned grouped.
+ add docstring for tn.contract_compressed and by default pick up
important settings from the supplied contraction path optimizer
(max_bond and compress_late)
+ add Tensor.rand_reduce for randomly removing a tensor index by
contracting a random vector into it. One can also supply the value "r"
to isel selectors to use this.
+ add fit-zipup and fit-projector shorthand methods to the general 1d
tensor network compression function
+ add MatrixProductState.compute_local_expectation for computing many
local expectations for a MPS at once, to match the interface for this
method elsewhere. These can either be computed via canonicalization
(method="canonical"), or via explicit left and right environment
contraction (method="envs")
+ specialize CircuitMPS.local_expectation to make use of the MPS form.
+ add PEPS.product_state for constructing a PEPS representing a product
state.
+ add PEPS.vacuum for constructing a PEPS representing the vacuum
state | 000 … 0 ⟩ .
+ add PEPS.zeros for constructing a PEPS whose entries are all zero.
+ tn.gauge_all_simple: improve scheduling and add damping and
touched_tids options.
+ qtn.SimpleUpdateGen: add gauge difference update checking and tol and
equilibrate settings. Update .plot() method. Default to a small cutoff.
+ add psi.sample_configuration_cluster for sampling a tensor network
using the simple update or cluster style environment approximation.
+ add the new doc {ref}ex-circuit-sampling

- Switch to testing in multibuild: The obs runtime requirement
resolver deals with numba/numpy blockage more gracefully than
trying to resolve a BuildRequires on them. Numba 0.60 is
restricted to Numpy < 2.1 right now.
* Update requirements
-------------------------------------------------------------------
Sat Aug 31 11:54:18 UTC 2024 - Dirk Müller <dmueller@suse.com>

and use these for `CircuitMPS.sample` and
`CircuitPermMPS.sample`.

* add `edges_1d_chain` for generating 1D chain edges

MPO building

leaves) as the target object to optimize.
* `TNOptimizer` can now directly optimize `Circuit` objects,
returning a new optimized circuit with updated parameters.
* `Circuit`: add `.copy()`, `.get_params()` and `.set_params()`
interface methods.
* Update generic TN optimizer docs.

center tracking.
* add `CircuitPermMPS`
* add `MatrixProductState.gate_nonlocal` for applying a gate,
supplied as a raw matrix, to a non-local and arbitrary number
of sites. The kwarg `contract="nonlocal"` can be used to
force this method, or the new option `"auto-mps"` will select
this method if the gate is non-local ({issue}`230`)

an MPS, and immediately compressing back to MPS form using
`tensor_network_1d_compress`

an MPO which only has tensors on a subset of sites with (by
default) identities

the TN to act on a subset of the full ``L`` sites.
* add `TensorNetwork.drape_bond_between` for 'draping' an
existing bond between two tensors through a third
* add `Tensor.new_ind_pair_with_identity`

builders (`TN_classical_partition_function_from_edges`) now
all support `outputs=` kwarg specifying non-marginalized
variables
* add simple dense 1-norm belief propagation algorithm `D1BP`
* add `qtn.enforce_1d_like` for checking whether a tensor
network is 1D-like, including automatically adding strings of
identities between non-local bonds, expanding applicability
of `tensor_network_1d_compress`

inplace*) version of `canonize`, to follow the pattern of
other tensor network methods. `canonize` is now an alias for
`canonicalize_` [note trailing underscore].
* add `MatrixProductState.left_canonicalize` as (by default
*non-inplace*) version of `left_canonize`, to follow the
pattern of other tensor network methods. `left_canonize` is
now an alias for `left_canonicalize_` [note trailing
underscore].
* add `MatrixProductState.right_canonicalize` as (by default
*non-inplace*) version of `right_canonize`, to follow the
