It seems like every tech business, once big enough, has feature creep like nuts.

"The third book, by Louis V. Gerstner, Jr., is precisely the story of how IBM avoided a cataclysm between 1993 and 1998. Gerstner was IBM’s CEO from 1993 to 2002. (…) In our industry, we hear plenty of entrepreneurs referring to the “second coming” of Steve Jobs to save Apple from bankruptcy in 1997, but very few remember that Gerstner pulled a similar feat with IBM just a decade prior, with a much larger payroll than Apple’s, and arguably, with much more at stake."

It turns out that IBM has an internal policy forbidding employees to write books about the company while they are employed by it. This is the major common point among the three authors of this month's Library article: they were all IBMers at some point, and they all wrote their books after leaving.

Dynamically Generated Decoherence-Free Subspaces and Subsystems on Superconducting Qubits
Decoherence-free subspaces and subsystems (DFS) preserve quantum information by encoding it into symmetry-protected states unaffected by decoherence. An inherent DFS of a given experimental system may not exist; however, through the use of dynamical decoupling (DD), one can induce symmetries that support DFSs. Here, we provide the first experimental demonstration of DD-generated DFS logical qubits. Utilizing IBM Quantum superconducting processors, we investigate two and three-qubit DFS codes co…

Quantum thermalization in contemporary quantum devices, in particular quantum computers, has recently attracted significant theoretical interest. Unusual thermalization processes, such as the Quantum Mpemba Effect (QME), have been explored theoretically.

Moreover, we experimentally validate our approach using IBM quantum devices, p…

We demonstrate algorithmic cooling on IBM-Q devices. We utilize inherent qubit noise to simulate the equilibration of an interacting spin system towards its ground state, when coupled to a dissipative auxiliary-spin bath. The steady-state correlations in the system are defined by the system Hamiltonian and are stable as long as the algorithm can be executed. In particular, we demonstrate the relaxation of system spins to ferromagnetic and antiferromagnetic ordering, controlled by the definition…

Prolate-oblate shape transitions and O(6) symmetry in even-even nuclei: A theoretical overview
Prolate to oblate shape transitions have been predicted in an analytic way in the framework of the Interacting Boson Model (IBM), determining O(6) as the symmetry at the critical point. Parameter-independent predictions for prolate to oblate transitions in various regions on the nuclear chart have been made in the framework of the proxy-SU(3) and pseudo-SU(3) symmetries, corroborated by recent non-relativistic and relativistic mean field calculations along series of nuclear isotopes, with param…

First Hitting Times on a Quantum Computer: Topological Effects and Dark States
We investigate a quantum walk on a ring represented by a directed triangle graph with complex edge weights and monitored at a constant rate until the quantum walker is detected. To this end, the first hitting time statistics is recorded using unitary dynamics interspersed stroboscopically by measurements, which is implemented on IBM quantum computers with a midcircuit readout option. Unlike classical hitting times, the statistical aspect of the problem depends on the way we construct the measur…
