How is this not clearly communicated anywhere (at least I didn’t saw it in any of the news / messages / posts about this that I read today), but I need you and Scott Aaronson to make me aware of this? 😅

Is #ScienceSky a thing yet? 👀

Dokumentation & Reportage: Wir waren in der AfD – Aussteiger berichten | ARD Mediathek Wir waren in der AfD – Aussteiger berichten | Video | 'Wir waren in der AfD' ist die Innensicht einer Partei, die sich in den vergangenen Jahren immer weiter radikalisiert hat und zugleich ein Film ...

Danke fürs teilen!
Den letzten Punkt 5, „Zustimmung zu den Positionen der AfD muss zu gesellschaftlicher Ächtung führen“, finde ich allerdings etwas problematisch.
„Radikalisierung passiert dann, wenn keine Hand mehr gereicht wird“, siehe (Minute 2:50):

Spannend, danke für den interessanten Thread! :)

Danke für die Tipps!

Mails unterschreiben würde ich als nicht-nerdig beschreiben, danke! :)
Wo würde man denn idealerweise seinen öffentlichen Schlüssel platzieren, damit Empfänger die Möglichkeit haben meine Unterschrift zu prüfen. Persönliche Website, oder…?

Interessant. Was wären denn straightforward use cases für einen PGP key für nicht-nerdige Anwendungen, die man im Alltag so nutzt?

While I still love the talk from William Oliver at Q2B 2021, I wonder if there is a similar great and more up-to-date talk available online. Does anyone have a good reference?

8/8 All in all: photons are cool. 😎
Let's do great things with them.

Quantum computational advantage with a programmable photonic processor - Nature Gaussian boson sampling is performed on 216 squeezed modes entangled with three-dimensional connectivity5, using Borealis, registering events with up to 219 photons and a mean photon number of 125.

7/ Proof of the quantum advantage: it's not just theoretical. PQC systems have manifested their potential in real experiments, showing a quantum computational advantage in several cases (Jiuzhang, Borealis).

6/ Diverse computational schemes: PQC proves versatile in performing various QC techniques, ranging from universal schemes like MBQC to non-universal ones such as boson sampling. Moreover, PQC is adaptable to classical photonic (aka optical) computing.

5/ Scalability & Compatibility: PQC systems are compatible with many existing photonic technologies, and promise great scalability due to the maturity of the photonics industry and the progress in photonic integration.

4/ Quantum communication: Photons are required anyway for quantum communication over optical networks, and distributed or modular computing approaches using optical links.

3/ Precision in manipulation: With the ability to be manipulated with high precision, photons have enabled high-fidelity single-qubit operations for decades.

2.5/ (Notice: We will most likely have to cool the photodetectors that are ultimately used in PQC systems. And when in the end the whole PQC system is integrated on a single chip, the whole chip therefore has to be cooled, but that's another story.)

2/ Operating temperature: A significant logistical advantage is that photons retain their quantum properties at room temperature. As a result, PQC systems don't need to be cooled to cryogenic temperatures (like many other QC architectures), which greatly reduces the implementation effort.

1/ Decoherence: Photons are nearly decoherence-free due to their weak interaction with their environment. This property allows many computations to be performed within a single qubit lifetime, increasing the robustness of PQC.

Among the various quantum computing architectures, photonic quantum computing (PQC) is emerging as a promising candidate. This is, as photonic quantum computing systems offer plenty of benefits. A thread. 🧵

6/6 All in all: Not only is it fascinating to work on a technology with such (potentially) immense impact on society, but it is also a fun intellectual challenge to work and think in the world of quantum mechanics.

5/ QC are leveraging quantum mechanical phenomena: superposition, entanglement, and quantum interference. This exponentially expands the computational space and allows operations to be performed in parallel.

4/
- material science and chemistry: speeding up the discovery of new materials and drugs with desired properties.
- ML and AI: promoting the processing of vast datasets and complex models
- finance: trading optimization, risk profiling, targeting and prediction
- etc. etc.

3/ QC will have a large impact in different areas:
- cryptography: threatening current encryption standards.
- optimization: solving previously unsolvable logistical optimization issues.

2/ One quantum technology is Quantum Computing (QC), which is a novel computing paradigm that allows to solve problems that are practically unsolvable for classical computers (or it would at least take them millennia).

1/ Quantum technologies are going to fundamentally change how information is processed, communicated and measured and hold the potential to emerge as the key technologies of the modern information society.

Why to write a master thesis on quantum computing? A motivational thread. 🧵
