Where’s my qubit? Scientists develop technique to detect atom loss
Quiet quitting isn’t just for burned out employees. Atoms carrying information inside quantum computers, known as qubits, sometimes vanish silently from their posts. This problematic phenomenon, called atom loss, corrupts data and spoils calculations.
But Sandia National Laboratories and the University of New Mexico have for the first time demonstrated a practical way to detect these “leakage errors” for neutral atom platforms. This achievement removes a major roadblock for one branch of quantum computing, bringing scientists closer to realizing the technology’s full potential. Many experts believe quantum computers will help reveal truths about the universe that are impossible to glean with current technology.
“We can now detect the loss of an atom without disturbing its quantum state,” said Yuan-Yu Jau, Sandia atomic physicist and principal investigator of the experiment team.
We Will Never Have Enough Resources For Teleportation | The Real Science of Scifi

Star Trek brought us so much scifi tech that we have been waiting to see come to life and one of the biggest dreams of all is teleportation! To boldly go… to the other side of the world without an 18 hour flight!
This is the second episode in a series about Scifi Tech we’ll never have…soz!
Today we’ll talk about matter vs information, how quantum teleportation actually works, how much information a human body contains, how we would measure that information and transfer it and ultimately, that it all comes down to an identity crisis.
Chapters:
00:00 Introduction.
02:32 For the love of scifi.
07:20 Quantum information.
11:46 Quantum teleportation.
16:19 The human factor.
20:20 Heisenberg compensators.
22:13 The measurement destruction problem.
24:15 The timing problem.
25:53 The data problem.
30:58 The unavoidable energy cost.
33:11 The identity question.

Some physicists believe that human consciousness is somehow linked to the indeterministic element of quantum physics. But according to a surprising new argument that just appeared on the arXiv, a world where everything is ruled by quantum physics is incompatible with the idea of free will. Let’s take a look.

Scientists build ‘most accurate’ quantum computing chip ever thanks to new silicon-based computing architecture
Researchers say they have created the world’s first scalable atomic quantum processor that achieves record-breaking 99.99% fidelity.
Why quantum computers have memory problems over time
A team of Australian and international scientists has, for the first time, created a full picture of how errors unfold over time inside a quantum computer—a breakthrough that could help make future quantum machines far more reliable.
The researchers, led by Macquarie University’s Dr. Christina Giarmatzi, found that the tiny errors that plague quantum computers don’t just appear randomly. Instead, they can linger, evolve and even link together across different moments in time.
The team has made its experimental data and code openly available, and the full study is published in Quantum.
Scientists crack the atomic code behind single-photon quantum emitters
This achievement removes one of the biggest roadblocks in quantum materials science and brings practical quantum devices much closer to reality.
Quantum emitters work by releasing single photons, individual packets of light, on demand. This ability is critical because quantum technologies rely on absolute control over light and information.
The problem has always been visibility and control. The exact atomic defects responsible for these emitters are incredibly small and difficult to observe. Scientists could either study how they emit light or examine their atomic structure—but not both at the same time.
