Russian Scientists Use Supercomputer To Probe Limits of Google’s Quantum Processor

CPQM’s quantum information processing laboratory collaborated with the CDISE supercomputing team “Zhores” to simulate Google’s quantum processor. By reproducing noise-free data based on the same statistics as Google’s recent experiments, the team was able to point out the subtle effects lurking in Google’s data. This effect is called an accessibility defect and was discovered by the Skoltech team in past work. The numbers confirm that Google’s data is on the edge of the so-called density-dependent avalanche, which means that future experiments will require more quantum resources to perform quantum approximation optimization. The results were published in the leading journal “Quantum” in the field. From the early days of numerical calculations, quantum systems have become extremely difficult to simulate, although the exact reason is still an active subject of research. Nevertheless, classical computers clearly have inherent difficulties in simulating quantum systems, which prompted several researchers to change their views. Scientists such as Richard Feynman and Yuri Manin speculated in the early 1980s that the unknown components that seemed to make quantum computers difficult to simulate with classical computers could themselves be used as computing resources. For example, quantum processors should be good at simulating quantum systems because they are governed by the same basic principles. This early idea eventually led Google and other tech giants to create prototype versions of the long-awaited quantum processors. These modern devices are prone to errors, they can only execute the simplest quantum programs, and each calculation must be repeated many times to average the error to finally form an approximation. One of the most studied applications of these contemporary quantum processors is the quantum approximation optimization algorithm, or QAOA (pronounced “kyoo-ay-oh-AY”). In a series of dramatic experiments, Google used its processor to probe the performance of QAOA with 23 qubits and three adjustable program steps. In short, QAOA is a method designed to approximate the optimization problem of a hybrid setup composed of a classical computer and a quantum coprocessor. Prototype quantum processors such as Google’s Sycamore are currently limited to performing noisy and limited operations. Using hybrid settings, the hope is to alleviate some of these system limitations and still restore quantum behavior to take advantage of, making methods such as QAOA particularly attractive. Skoltech scientists have recently made a series of discoveries related to QAOA, for example, please refer to the article here. What stands out is the impact that fundamentally limits the applicability of QAOA. They show that the density of the optimization problem—that is, the ratio between its constraints and variables—is the main obstacle to achieving approximate solutions.

While a Punjabi vocalist croons, PM Modi replicates Diljit Dosanjh’s beats and beats the table like a dholak. Observe

Prime Minister Narendra Modi recently met acclaimed singer- actor Diljit Dosanjh, describing their interaction as “very memorable.” 
Prime Minister Narendra Modi met singer-actor Diljit Dosanjh and lauded him as “a combination of talent and tradition.” During the “memorable’ meeting”, the two discussed music, culture, and India’s vibrancy, including yoga.

Diljit, PM Modi match beats

During the meeting, PM Modi praised Diljit for his achievements, saying, “When a boy from a small village in Hindustan shines on the global stage, it feels amazing. Your family named you Diljit, and you keep on winning people’s hearts, just as your name suggests.”

Diljit responded, “We used to read that ‘Mera Bharat Mahan’ (My India is great), but when I travelled across India, I realised why people say this.” PM Modi highlighted India’s diversity, saying, “India’s vastness is its strength. We are a vibrant society.”

Diljit added, “The greatest magic in India is yoga.” PM Modi agreed, saying, “Those who have experienced yoga know its power.”

The singer-actor also admired PM Modi’s personal journey, saying, “I had watched your interview, sir. The position of Prime Minister is great, but behind it, there is a mother, a son, and a human being. Many times, this half-truth is much larger when you carry your mother and the sacred Ganga with you. That touches the heart.”

Diljit then sang a song on Guru Nanak, as PM Modi listened intently, beating the adjacent table like a dholak, matching his beats with Diljit’s.

Diljit, PM Modi express grattitude

After the meeting, Diljit Dosanjh expressed his gratitude, calling it a “fantastic” way to start the year. He posted on X, “A fantastic start to 2025. A very memorable meeting with PM @narendramodi Ji. We talked about many things, including music, of course!”

PM Modi responded to Dosanjh’s post, describing their meeting as “a great interaction.” He said, “A great interaction with Diljit Dosanjh! He’s truly multifaceted, blending talent and tradition. We connected over music, culture, and more.”

Diljit recently concluded his Dil-Luminati tour in India with a grand performance in Ludhiana. Throughout his concerts at various venues, the singer aimed to address important social issues during his performances.

In a lighthearted and endearing moment, Prime Minister Narendra Modi was seen enjoying the beats of a Punjabi vocalist, tapping the table in rhythm like a dholak player during a recent cultural event. The video, which has since gone viral, showcases PM Modi replicating the infectious energy of Diljit Dosanjh’s iconic beats, capturing the essence of Punjabi music’s vibrancy and rhythm.

The event brought together various cultural performers, with one Punjabi vocalist stealing the spotlight. As the singer crooned traditional Punjabi tunes, PM Modi, seated among other dignitaries, began enthusiastically tapping the table in sync with the music. His gestures resembled a seasoned dholak player, displaying his spontaneous connection with the pulsating beats.

The audience present erupted in applause, cheering on the Prime Minister’s engaging participation. Social media users were equally charmed, with many praising Modi’s ability to connect with the cultural diversity of India. “Modi Ji has the rhythm of a true Punjabi!” one user commented, while another said, “This is the energy we love to see in our leader.”

The moment also highlighted PM Modi’s commitment to celebrating India’s rich cultural heritage. His natural enjoyment of the performance reflects his appreciation for the art and music that unify the diverse communities of India.

Such lighthearted and relatable gestures from leaders often resonate deeply with the public, making them feel connected on a personal level.
