Decoding Qubit Decoherence: The Role of Material Defects
![Computed tunnel splitting for oxygen-hydrogen and oxygen-deuterium defects exhibits an exponential dependence on the mass-scaled phonon coordinate $Q^{\prime}=Q\sqrt{m/m\_{\mathrm{Nb}}}$, as demonstrated using a four-dimensional Hamiltonian, with distinct behaviors observed for vibrational masses corresponding to vanadium (circles), niobium (squares), and tantalum (triangles), aligning with existing experimental data from reference [29].](https://arxiv.org/html/2512.18156v1/x3.png)
A new theoretical framework details how lattice distortions and anharmonic couplings within superconducting qubit materials drive decoherence, offering insights for improved qubit design.

This list isn’t just about life simulation games; it also features role-playing and action-adventure titles that let you immerse yourself in a world, make meaningful decisions, and create a unique, personal experience.

The original Spyro the Dragon game came out on PlayStation in September 1998. It was followed by two sequels, Spyro 2: Ripto’s Rage in 1999 and Spyro: Year of the Dragon in 2000. Insomniac Games first developed the Spyro games, but other studios like Eurocom and Krome Studios also contributed to the series throughout the 2000s. More recently, Toys for Bob took over in 2018, and they’ve released Spyro Reignited Trilogy, Crash Bandicoot 4: It’s About Time, and Crash Team Rumble. Most Spyro games are 3D platformers where players control the purple dragon as he glides, charges through levels, and breathes fire at enemies. Spyro is a beloved PlayStation character, remembered alongside other icons like Crash Bandicoot.

Steam has a lot of open-world survival games where you build and craft things. Popular titles like No Man’s Sky, Subnautica, and Rust are well-known, but Green Hell is a fantastic game that hasn’t always gotten the recognition it deserves. Thankfully, that’s changing, and more and more people are discovering Green Hell on Steam.

I watched as the My Hero Academia anime began back in 2016, and just recently finished in 2025. For nearly a decade, Studio Bones animated the series, and it really felt like their most important new project. It seemed like a huge undertaking for them, and many fans agreed.

A new study sheds light on the surprisingly subtle problem of unreliable tests in quantum software development.

The Elbaf arc is expected to begin in the One Piece anime in April 2026. However, before that happens, there will be a significant break in the series. This break will start at the end of December, after the Egghead arc finishes. Breaks like this are likely to become common, as One Piece has been airing weekly for nearly 30 years, and the production schedule is changing.

December 2025 was full of activity in Pokémon GO, with Niantic consistently adding new events and things to do each week. The December Community Day allowed players to catch all the Pokémon that were featured in previous Community Days throughout the year. Players also had the chance to catch Nacli and its evolutions for the first time, and a Winter Fest event is currently underway. Plus, a promo code is available for free in-game items.

Not all changes in games are immediately noticeable, but we can still follow how they develop. Regardless, open-world games deserve recognition for their innovative designs and how they’ve inspired countless others. We can expect to see even more games in the future that build on these ideas.

Since the original game came out in 1987, the Final Fantasy series has delighted players with epic role-playing adventures. Over the last 31 years, several Final Fantasy anime shows and movies have also been released, mostly as direct-to-video OVAs. There’s been one full-season anime series and a movie as well, and recently, another project that seemed stalled has been revived.
