Update main: link to new repo, before 0.3.5 release. (#273)

* Update develop to catch up with main version 0.3.3 (#249) * Fix link of fig in qchem & excited states notebook (#250) * allow single flip index dis for qcc (#247) * allow single flip index dis for jkmn * Richardson extrapolation: bug fix + error estimation (#252) * Bugfix: DMET with QCC (#253) * iQCC using only Clifford circuits notebook (#254) * pUCCD ansatz (#251) * UHF reference (#240) * uhf implementation with VQESolver functionality * support for all types of orbital freezing * add active_spin and uhf attributes to SecondQuantizedDMETFragment * add spin to adapt_ansatz arguments * added multi-product, grid_circuits and discrete_clock (#257) * added multi-product, grid_circuits and discrete_clock * translation to pennylane (#260) * tangelo to pennylane format translation Co-authored-by: Valentin Senicourt <[email protected]> * bump testing version to 3.8 (#262) Updating python version to 3.8 in automated tests, as 3.7 is no longer maintained by the Python dev team * Auto threshold cutoff for small coefficients in LCU (#261) * check for small value lcu * changed to keep same vector length but apply no operations * Openshell DMET (#208) * Open-shell DMET. * Fix for get_rdm CCSD. * Added NAO localization. * Added LiO2 spin=1 DMET test. * Added UHF MF for DMET. New get_rdm for VQESolver. * Save mid-circuit measurement (#256) * A flag now allows users to save mid-circuit measurements for each shot run. Co-authored-by: Valentin Senicourt <[email protected]> * Fix for IBMQConnection (#264) * Updated copyright year to 2023 (#267) * added draw method to circuit (#266) * added draw method to circuit (warning about font comes up in linux env) * Cirq, qulacs, pennylane and projectq operator translation functions (#268) * Support to bidirectional translation of operators for cirq, qulacs, PennyLane, projectq. * Fixed a bug in QulacsSimulator.expectation_value_from_prepared_state. * Important bug in qiskit -> tangelo op translation fixed * Fixed identity operator evaluation and extended the accepted input types in compute_rdms (#269) * Compute RDMs function can now hangle both term formats (string and openfermion tuple). * Unhashable list for of -> conversion to tuples. * Handling all the inputs in compute_rdms. * Temporarily disabling OS-DMET (#271) * Temporarily disabling for code verification purpose, as the implementation seems to return very odd and incorrect results for simple systems. * Link to new example repo * Update README.rst * Revert changes that broke tests (#275) * reverted changes that broke tests --------- Co-authored-by: AlexandreF-1qbit <[email protected]> Co-authored-by: James Brown <[email protected]> Co-authored-by: KrzysztofB-1qbit <[email protected]>

+We have a `dedicated repository <https://github.com/goodchemistryco/Tangelo-Examples>`_ for examples and tutorials !

+We wrote a number of them, and tried to provide material that doesn't just explain how to use the software, but provides insights into the complex topics of chemistry, quantum computing, and digs into the challenges we encountered in our previous hardware experiments.
